 # Ballance Properties
 
-!!! info "Work in Progress"
+The Ballance attributes are distinct from the Virtools attributes, which are a set of attributes dedicated to Ballance mapping. These properties are hosted in the scene and do not change within the same scene (mapping does not involve scene switching in Blender). The panels related to the Ballance property can be found in the `Scene` properties panel, as shown below, and they are:
-    This part of manual still work in progress.
+
+* `Ballance Elements` panel (red arrows), corresponding to Ballance elements
+* `BME Materials` panel (green arrow), corresponds to BME materials.
+* `Ballance Map` panel (blue arrow), which corresponds to the Ballance map information.
+
+Among these, only the Ballance Map information is the one you need to focus on, the other attributes are not normally of interest, except in the case of errors in some of the materials or meshes in the map.
+
+![](../imgs/ballance-properties.png)
+
+## Ballance Map Information
+
+Ballance Map infomation currently has only one option, Sector (map sector count). This attribute indicates the final desired number of sectors for the current map. This attribute is mainly used to work around the bug of exporting map, see the [Import and Export Virtools Document](./import-export-virtools.md) section for details on the bug.
+
+The only thing you need to do is to check if this field is the number of sectors you expect before exporting the final map. Note that although you can set this field at the beginning of creating your map, there are other features in BBP that may modify this field, such as adding elements, importing Virtools documents, etc. For example, if you have a map with sector 3 specified and you are adding an element that belongs to sector 4, this value will automatically increase to 4. Similarly, when importing a Ballance map with a total of 4 sectors, this value will also increase to 4 (if the previous value was less than 4). The main reason for doing this is so that users can use this plugin without perceiving this value, especially when making slight modifications to some existing maps. Doing so, however, may not meet the user's needs in some cases, so it is still recommended that you check this field before exporting.
+
+## Ballance Elements
+
+Ballance Elements keep a record of the meshes of all the elements you have added using the BBP Add Elements feature. Meshes generally take up the largest amount of data in a 3D file, so reducing the number of meshes, i.e. by sharing meshes between objects of the same shape, can drastically reduce the size of the map file. When you use BBP to add an element-related function, it will first try to get the element's mesh from here, and if there is no corresponding mesh, it will be loaded and recorded here.
+
+This panel is for viewing only, not editing. If you have accidentally modified the meshes of a BBP-added element (which should not have been modified in the first place) and want to restore its original shape, just click `Reset Ballance Elements` to reset all the element meshes in the list to their correct state.
+
+## BME Materials
+
+Similar to the Ballance Elements, records the materials used when adding floor using BME. This is also designed so that materials can be reused, so that you don't need to create a set of materials associated with each object you create, greatly reducing the number of duplicate materials.
+
+This panel is for viewing only, not editing. When you accidentally modify BME related materials (which should not have been modified) and want to restore them, just click `Reset BME Materials` to reset all materials in the list to their correct state.

+In the Normal Platform dialog, we can first see that it asks us to provide the length and width of the floor, which determines the size of our platform, and there is a text description to help you understand what this property controls.
+
+Then it also asks us to provide the height of the platform, which defaults to 5, which is the default height of the floor in Ballance. Anything less than 5 creates a thin floor similar to the one in the "The Devil Dragon" map, and anything greater than 5 creates a very high floor wall similar to the one in the "Exaggeratedly Dense Space Station" map.
+
+Finally, it tells us which sides of the floor we need to configure to display. Note that Top and Bottom are the top and bottom surfaces along the height direction (Z axis), while Front, Back, Left, and Right are the front, back, left, and right surfaces when looking down with your head on the -X axis and your eyes on the -Z axis. You may notice that there is a perspective cube in the center of these six face buttons, and in fact the positions of these six face options correspond to the positions of the six faces of this perspective cube.
+
+## Tips
+
+Each floor type has a different number of configuration entries, so for different floor types, you will need to follow the configuration hint text to understand what the corresponding configuration does. Some floor types may have a large number of configuration entries, while others may have no configuration entries at all.
+
+The default values for the floor type configuration are set to the values that were most commonly used when the floor was created. The values are reset to the defaults each time the floor type is switched or recreated.

 # Compile and Distribute Plugin
 
-!!! info "Work in Progress"
+This page will guide you in compiling the plugin as well as distributing it.
-    This part of manual still work in progress.
+
+## Compiling LibCmo with BMap
+
+BBP's Virtools file native import/export functionality relies on BMap and its Python binding PyBMap. In order to distribute the plugin, we need to first compile BMap and its predecessor LibCmo, and before doing so, you need to check the version of BMap you need. Because BBP doesn't always use the latest version of BMap, e.g. if you're compiling an older version of BBP, it's obviously not possible to rely on the latest version of BMap. BMap is constantly being upgraded, and the functionality it provides is constantly changing, and different versions of BMap are incompatible. BBP usually states the version of BMap it uses at the time of release, but if BBP doesn't point it out, you may need to look for the most recent version of BMap that compiles with the version of BBP at the time of its release.
+
+After specifying the version, you need to visit [LibCmo GitHub repository](https://github.com/yyc12345/libcmo21). Then clone the project and use the Git command to go to the corresponding version (or just download the source code of the corresponding version). Then follow LibCmo's compilation manual to compile to get BMap. on Windows, you'll usually get the files `BMap.dll` and `BMap.pdb`. On Linux, it will be `BMap.so`.
+
+Then we need to configure PyBMap, which comes with LibCmo. Please follow the manual of PyBMap to combine the compiled binary BMap library with PyBMap. That is to complete the PyBMap configuration.
+
+Then we need to copy the configured PyBMap to our project under `bbp_ng/PyBMap` to complete this step.
+
+## Generate Thumbnails and Compress JSON
+
+BBP comes with a built-in set of custom icons, as well as the JSON files needed by its component BME to describe the structure. By batch generating thumbnails and compressing JSON operations, the size of these parts can be reduced, making them suitable for loading in Blender and easier to distribute.
+
+Go to the `bbp_ng/tools` folder and run `python3 build_icons.py` which will batch generate thumbnails (this requires the PIL library, please install it via pip in advance). It actually generates thumbnails from the original images in the `bbp_ng/raw_icons` directory and stores them in the `bbp_ng/icons` folder. Running `python3 build_jsons.py` will compress the JSON, which actually reads, compresses, and writes the raw JSON files from the `bbp_ng/raw_jsons` directory into the `bbp_ng/jsons` folder.
+
+## Packaging
+
+Starting from Blender 4.2 LTS, plugins are packaged using Blender's own packaging feature.
+
+Assuming that the final output file is `redist/bbp_ng.zip`. If you are in the root directory of the project, execute the `blender --command extension build --source-dir bbp_ng --output-filepath redist/bbp_ ng.zip` command in a command line window to finish packaging. Please note `blender` is the executable Blender program.
+
+Blender will package the plugin according to the instructions in `blender_manifest.toml` with the following files excluded:
+
+* `bbp_ng/raw_icons`: raw thumbnail folder.
+* `bbp_ng/raw_jsons`: raw JSON folder.
+* `bbp_ng/tools`: tools for compiling.
+* `bbp_ng/.style.yapf`: code style description file.
+* `bbp_ng/.gitignore`: gitignore
+* `bbp_ng/icons/.gitkeep`: folder placeholder
+* `bbp_ng/jsons/.gitkeep`: folder placeholder
+
+## Generating Help Documentation
+
+Although this project will utilize the GitHub Page feature to provide help documentation, sometimes you may need to provide an offline version of the help documentation, this section will explain how to generate an offline version of the help documentation.
+
+First you need to install `mkdocs` and `pymdown-extensions` via pip. Then go to the `docs` folder and run `mkdocs build --no-directory-urls`. After running the command you get a folder called `site`, which is the help documentation that can be viewed offline.

 # Add Component
 
-!!! info "Work in Progress"
+In the 3D view, click `Add - Components` to expand the Add Components menu. The menu is shown on the left side of the image below.
-    This part of manual still work in progress.
+
+![](../imgs/component-adder.png)
+
+The right side of the image above shows the interface for adding some components, which will be described in turn, from top to bottom on the right side are: Add Checkpoint, Add Nong Extra Point, Add Nong Ventilator, Add Ventilator Series, Add Sector Pair.
+
+## General Components
+
+In the Add Components menu, under the `Basic Components` category, you can add general components. For most components, adding an component requires specifying the sector it belongs to, indicating that the component is only active in that sector. However, there are some exceptions:
+
+* PS_FourFlame: the 4-flame platform at the start of the level, which is globally unique and therefore has no sector attribute.
+* PE_Ballon: the ship at the end of the level, globally unique and therefore has no sector properties.
+* PC_TwoFlames: the checkpoint for the sector, with a sector attribute. However, it should be noted that its sector attribute refers to which sector it is going to check, for example, specifying a sector attribute of 1 means that it is the checkpoint of the first sector, i.e. the start of the second sector, and the second sector will be opened after passing it.
+* PR_Resetpoint: the reset point of the sector with the sector attribute. However, it is important to note that the sector attribute indicates which sector it is the respawn point of. It follows that when PC_TwoFlames and PR_Resetpoint appear in pairs, PR_Resetpoint is always labeled 1 greater than PC_TwoFlames.
+
+!!! info "Automatic name conflict detection"
+    A portion of the components have unique names in a Ballance map, e.g., there is and can only be one start point and one ending ship, only one checkpoint and one respawn point can exist in the same sector, etc.
+    
+    BBP provides a name detection function when creating these components, and if the name already exists, it will be shown in text below when creating to remind users not to create duplicates. As shown in the upper right corner of the display image above as an example, it is trying to add a PC_TwoFlames that already exists and receives a warning.
+
+## Add Nong Components
+
+In the Add Components menu, under the `Nong Components` category, you can add nong components. We only provide two common types of nong components: Nong Extra Point and Nong Ventilator.
+
+### Nong Extra Point
+
+To add a nong extra point, you need to specify the number of nong extra point and the sector number of it. It also will automatically rotate the nong extra point with a slight degree one by one to make the nong extra point look better in the game.
+
+### Nong Ventilator
+
+Nong ventilator are also added by specifying the number of nong ventilators and the sector number of ventilators. The difference is that we have provided some preset values for constructing nong ventilator that will just blow up wood or stone balls, and if you are not satisfied with these preset values, you can still enter the number yourself.
+
+!!! info "Ventilator arrays are also possible"
+    Did you know that nong ventilators are also possible by setting the offset to 0 when adding a ventilator series? The nong ventilator creation here is just providing some preset values.
+
+## Add Series Components
+
+In the Add Components menu, under the `Series Components` category, you can add series components (aka. component array). We only provide two types of commonly used series: fTilting Block Series and Ventilator Series.
+
+### Tilting Block Series
+
+Tilting Block Series requires you to provide the number of tilting blocks and the number of tilting blocks, and you can also adjust the spacing between adjacent tilting blocks, the default spacing is taken from the game.
+
+### Ventilator Series
+
+The ventilator series also requires sector number and count of ventilators, however it provides a 3D offset so that you can build a vertical or horizontal ventilator series. The default offset values are taken from the in-game values for vertical ventilator series.
+
+## Add Components Pair
+
+In the Add Components menu, under the `Components Pair` category, you can add pairs of components. Currently, only one type of pairs can be added: Sector Pair.
+
+### Sector Pair
+
+To add a Sector Pair, you need to enter a Sector number and it will automatically generate a pair of the checkpoint and respawn point components for you. For example, if you enter 1, it will automatically generate a 4-flame start point and a respawn point for Sector 1, if you enter 2, it will generate a checkpoint for Sector 1 and a respawn point for Sector 2, and so on.
+
+!!! info "Automatic name conflict detection"
+    Similar to normal component additions, sector pair additions have the same name conflict detection. As an example, the lower right corner of the image above shows that the sector pair for sector 1 already exists and does not need to be added.

 # Configure Plugin
 
-!!! info "Work in Progress"
+!!! info "The plugin must be configured first"
-    This part of manual still work in progress.
+    Some of the configurations of the BBP plugin are closely related to the use of the plugin, and only when the BBP plugin is correctly configured can the full functionality of the BBP plugin be used.
+
+    **Whether installing for the first time or updating**, reconfiguring the plugin is essential to ensure that the settings are correct.
+
+## Open the Configuration Panel
+
+Open Blender, select `Edit - Preferences`, in the window that opens go to the `Add-ons` tab and find the BBP plugin in the list. Its name is `Ballance Blender Plugin`. Make sure that the checkbox next to the name is checked, which means that the plugin is enabled. Click on the triangular arrow to the left of the checkbox to expand the plugin details to enter the configuration panel as shown in the figure.
+
+![](../imgs/config-plugin.png)
+
+## Start to Configure
+
+The BBP plugin currently has 2 settings to configure.
+
+### External Texture Folder
+
+Please fill in the `Texture` directory of Ballance, from which the plugin will use the external texture files (i.e. the ones Ballance originally came with). Click on the folder button on the right to browse the folders and select it.
+
+This is crucial for BBP to work properly, and only if it is filled out correctly will BBP not make errors during operation.
+
+### No Component Collection
+
+When importing and exporting BM files, objects that are in a collection with this name will be forced to be specified as No Component. leaving this blank means that this feature is not needed. This feature is usually used for forced element model replacement.
+
+!!! warning "This setting is not required at this time"
+    Since BBP 4.0 supports native import/export of Virtools files, the BM file import/export function is no longer used. Therefore, this field is no longer useful and does not need to be filled in.

 # Group Operation
 
-!!! info "Work in Progress"
+## Select by Group
-    This part of manual still work in progress.
+
+`Ballance - Select by Virtools Group` provides a feature to filter by Virtools grouping data.
+
+The feature starts with 5 different selection strategies that match Blender's selection methods exactly (Set, Extend, Subtract, Invert, Intersect). Simply use it like a Blender selection. Then, select the name of the group you need and start a selection or filter.
+
+!!! note "About pattern selection"
+    If you can, use the Subtract or Intersect modes whenever possible. Because this avoids analyzing too many objects. For example, selecting a general range first and then filtering using Intersect mode is more efficient than using Set mode directly.
+
+## Quick Grouping
+
+The BBP plugin adds the ability to quickly group objects in 2 places. The first is the object context menu: you can select a series of objects and right click to find the quick grouping feature in the object context menu. Second is the Objects menu in Outline view: you can right-click on a selection of objects in the Outline view to find the quick grouping feature. Both menus are shown below.

 # Import and Export Virtools Document
 
-!!! info "Work in Progress"
+!!! warning "This is experimental content"
-    This part of manual still work in progress.
+    Native importing and exporting of Virtools documents is experimental content for the BBP plugin, it may have many problems, see the [Report Issue](./report-bugs.md) section to learn more. When problems are encountered, please report them. the authors of the BBP plugin are not responsible for any consequences resulting from problems with the BBP plugin.
+
+## Import Virtools File
+
+Virtools files can be imported by clicking `File - Import - Virtools File`. Importing supports CMO, VMO and NMO files. Clicking on it will bring up the file opening window and show the import settings in the sidebar. First of all, you need to select the Virtools file to be imported, and then configure the import settings in the sidebar. After configuring the import settings, you can click Import to start the import, and wait for the status bar at the bottom of Blender to indicate that the import is complete.
+
+### Conflict Options
+
+The Conflict Options section indicates what to do when the importer encounters duplicate object names. There are 4 levels, for Object, Mesh, Material and Texture. There are 2 ways to handle it: Rename and Use Current. When Rename is selected and a duplicate name is encountered, a suffix will be added to the name to make it unique. By choosing Use Current, the import of the item from the file will be ignored and the item with the same name will be used instead, which already exists in the Blender document.
+
+!!! info "Differences from Virtools conflict resolution"
+    Compared to the conflict resolution dialog in Virtools, the conflict resolution options provided by the BBP plugin do not support replacement, and the granularity is not fine-tuned to individual instances, but only for an entire type. So you can't set a different conflict resolution for each instance of a conflict individually. However, this setting is sufficient for most scenarios.
+
+The default values for the options in the Conflict Options section are the solutions that are usually selected for import. Of course, special settings are needed for special import situations, e.g. if you are importing an externally exported element model from the original version, you may be able to use Use Current option in material options instead of making a copy. The correct use of the conflict options is a matter of mapping experience and is not taught in this manual.
+
+### Virtools Params
+
+It is well known that Virtools uses a system-based multi-byte character encoding to process documents, and is therefore prone to what is known as garbling; Blender itself does not suffer from garbling, however, if we do not read a Virtools document with the correct encoding, the characters stored in it may still appear garbled when the Virtools document is imported into Blender. The Encodings property in the Virtools Params section specifies the encodings for reading Virtools documents. Multiple encodings can be specified, separated by a `;` (semicolon). Some common encodings are listed below:
+
+* 1252 (Windows only): Western European encoding used by Ballance.
+* 936 (Windows only): the default encoding for Chinese Windows system.
+* CP1252 (non-Windows): Western European encoding used by Ballance.
+* CP936 (non-Windows): the default encoding for Chinese Windows system.
+
+The encoding attribute is very important, if you set the wrong encoding, the names of the various objects imported into Blender will be unrecognizable.
+
+!!! warning "Encoding is a platform dependent setting"
+    According to the implementation of LibCmo, the underlying library used by BBP's Virtools documentation for the import module, the encoding attribute is a platform dependent setting. Under Windows, the [Windows Code Page](https://learn.microsoft.com/en-us/windows/win32/intl/code-page-identifiers) number is required here. Under other operating systems, LibCmo uses iconv for character encoding and decoding, so you need to use the legal [Iconv Encoding Identifier](https://www.gnu.org/software/libiconv/).
+
+## Export Virtools File
+
+Virtools files can be exported by clicking `File - Export - Virtools File`. Clicking on it will bring up the file opening window and show you the export settings in the sidebar. First of all, you need to select the location of the exported Virtools file, then configure the export settings in the sidebar, after configuring the export settings, you can click Export to start the export, and wait for the status bar at the bottom of Blender to indicate that the export is complete.
+
+### Export Target
+
+The Export Target section is used to determine which objects you need to export to a Virtools document. You can choose to export a collection or an object and select the corresponding collection or object below. Note that selecting a collection will export the objects in the internal collection as well, i.e. exporting nested collections is supported.
+
+### Virtools Params
+
+The Virtools Params section is similar to the one in the importing Virtools document; the Encodings property determines the encoding used when exporting a Virtools document.
+
+The Global Texture Save Option determines how textures that are set to Use Global are actually saved. In general, setting it to Raw Data will 100% guarantee that the saved Virtools document will contain the correct texture, but it may be larger, while setting it to External will minimize the size of the file, but there may be problems with the exported document not finding the texture file. We recommend that you specify how each material should be saved individually when you set it up, rather than relying on the global option to set it up. This option is for re-editing old maps that rely on the Global Texture Saving Option. It should also be noted that even though there is a Use Global option in this option, please **don't** select it or it will result in an error, because obviously you can't have a global option that then uses the global option's settings.
+
+The Use Compress property specifies whether saved documents are stored compressed. Compression can significantly reduce the size of a document, and on modern computer platforms, the performance loss caused by compression is almost negligible. When Use Compress is selected, an additional Compress Level attribute is displayed, which specifies the level of compression; the higher the value, the greater the compression rate and the smaller the file.
+
+### Ballance Params
+
+The Ballance Params section contains parameters that optimize the export process for Ballance-specific content.
+
+Successive Sector is an option to work around a bug that occurs when exporting groups of sectors. For some reason, if there are no elements in a sector (actually, no objects are grouped in a sector group), the export plugin thinks that the sector group doesn't exist and misses the export. And since Ballance determines the final sector, i.e. the sector where the spaceships appears, by incrementing the number of sectors from 1 to the last sector group that exists, the combination of the two causes Ballance to incorrectly determine the number of sectors in the map, and thus display the spaceships in the wrong sector, which is an export bug. when this option is checked, the exported document will be pre-defined according to the number of sectors specified in the Ballance Map information in the current Blender file. When this option is checked, the exported document will pre-create all of the sectors according to the number of sectors specified in the Ballance map information in the current Blender file before exporting, so that you don't miss creating some sector groups, and the spaceships will be displayed in the correct sectors.
+
+This option is usually checked when exporting playable maps, if you just want to export some models then you need to turn this option off, otherwise it will create a lot of useless sector groups in the final file.

 # Install Plugin
 
-!!! info "Work in Progress"
+## Determining the Version
-    This part of manual still work in progress.
+
+The principle of BBP's Blender support is to support the latest **LTS** version, and to spend some time migrating the plugin after the latest LTS version is released. The current plugin version **4.0** is based on Blender version **4.2.x**.
+
+Theoretically, BBP will work fine on other versions of Blender if no major changes have been made. For example you can try to run BBP plugin based on Blender 3.6 LTS on Blender 4.0. However, the developers of BBP do not deal with bugs that only appear in non-LTS versions. before installing the plugin, please select the appropriate version.
+
+## Uninstall the Old Plugin
+
+If you have used BBP before then you need to uninstall it first. Older versions of BBP are usually installed in the following locations:
+
+* `<Blender>/3.6/scripts/addons/ballance_blender_plugin`: BBP 3.0 or lower version.
+* `<Blender>/3.6/scripts/addons_contrib/ballance_blender_plugin`: BBP 3.0 or lower version.
+* `<Blender>/3.6/scripts/addons/bbp_ng`: BBP 4.0 internal test version
+* `%APPDATA%/Blender Foundation/Blender/3.6/scripts/addons/bbp_ng`: BBP 4.0 internal test version
+* `%APPDATA%/Blender Foundation/Blender/4.2/extensions/user_default/bbp_ng`: BBP 4.0 or higher version
+
+You just need to disable the plugin in Blender first (uncheck the box in front of the plugin name) and then delete these folders (if they exist) to uninstall the plugin completely. The `<Blender>` in the path refers to the location of your Blender installation. The `3.6` and `4.2` in the path are the version numbers of your Blender installation, which need to be adjusted according to the version you have installed, and subsequent occurrences of version numbers should be understood as the same meanings.
+
+!!! warning "Should not use Blender's plugin uninstall feature"
+    It is not possible to uninstall BBP using the plugin uninstall function on the Blender plugins page, because BBP loads the Virtools file read/write library BMap into Blender as soon as it is loaded by Blender (whether it is enabled or not). if you remove it while Blender is running, you will get an access denied error. Therefore you must manually delete the plugin directory after closing Blender.
+
+    If you are really not sure where the plugin is installed, you can find the `File` property in the Addons page of Blender's Preferences, and the folder it points to where the file is located is the folder to be deleted.
+
+!!! info "`ballance_blender_plugin` and `bbp_ng`"
+    `ballance_blender_plugin` is the module name of the old version of the BBP plugin (before version 4.0) and `bbp_ng` is the module name of the new version of the BBP plugin (after and including version 4.0). Both are provided in order to ensure that the user actually deleted the old version of the plugin.
+
+!!! info "`addons` and `addons_contrib`"
+    After Blender version 3.6 LTS, i.e. BBP version 3.3, Blender no longer supports Testing type plugins. As a result, the `addons_contrib` folder, which was dedicated to installing Testing plugins, is no longer used, and plugins need to be installed uniformly in `addons`. Both are provided to ensure that the user actually deletes the old version of the plugin.
+
+!!! info "`addons` and `extensions`"
+    In Blender version 4.2 LTS, Blender uses Extensions instead of Addons to describe plugins. This has resulted in a change in where plugins are installed. Both are provided in order to ensure that the user actually removes the old version of the plugin.
+
+## Download Plugin
+
+You can download the latest plugin via [the Release page of the GitHub codebase for this project](https://github.com/yyc12345/BallanceBlenderHelper/releases). Plugins are provided as ZIP archives.

 # Legacy Alignment
 
-!!! info "Work in Progress"
+`Ballance - 3ds Max Align` provides an alignment function similar to the way alignment works in 3ds Max.
-    This part of manual still work in progress.
+
+The so-called legacy alignment feature is a perfect reimplementation of the 3ds Max alignment operations in Blender. It makes it possible for many mappers who switch from 3ds Max to Blender to get up to speed faster and provides some convenient alignment operations. The image below shows legacy alignment in action.
+
+![](../imgs/legacy-align.png)
+
+## Usgae
+
+Legacy alignment supports aligning multiple objects to a single object by first selecting the objects to be aligned in turn, then selecting the reference object at the end of the alignment (i.e. making it the active object), and then clicking `Ballance - 3ds Max Align` to bring up the legacy alignment panel, after which you can start the alignment operation.
+
+## Introduction of the Panel
+
+In the panel, `Align Axis` specifies the axis you want to align to, you can multi-select here to specify more than one axis, without specifying any axis you will not be able to do the alignment operation, and thus you will not be able to click the `Apply` button.
+
+`Current Object` is the alignment reference object, which is the active object in the scene, usually the last object you selected. This option specifies what value you need to reference for alignment, with `Min` (minimum value on axis), `Center (Bounding Box)` (center of the bounding box), `Center (Axis)` (origin of the object), and `Max` (maximum value on axis) available. These options are consistent with the alignment options in 3ds Max.
+
+The `Target Objects` are the objects that are being aligned, there may be many of them, in this option it is also specified what values you need to refer to them for alignment. The options have the same meaning as `Current Object`.
+
+The `Apply` button, when clicked, will press the current page's configuration into the operation stack and reset the settings above, allowing you to start a new round of alignment operations without having to perform a legacy alignment again. The number of operations in the stack is shown below the `Apply` button.
+
+!!! info "What the Apply button does"
+    Understanding this part is not useful for mapping, and you don't need to read what's in this box unless you're interested.
+
+    By design, Blender doesn't support so-called "operations inside the Operator", but with a few tricks we simulated Apply effect similar to the one in 3ds Max.
+    
+    The Apply button is actually a specially displayed BoolProperty that listens to its value change event and, while avoiding recursive calls, records the current setting in a hidden CollectionProperty and resets its own value and displayed properties to make a visual "apply".

+
+This plugin currently supports two naming convention.  
+One is the Mapping Toolchain Standards described in the [Technical Information](./tech-infos.md) section, which is named `YYC Tools Chains` in this plugin.  
+The second is the naming standard used by [Imengyu/Ballance](https://github.com/imengyu/Ballance), named `Imengyu Ballance` in this plugin.
+
+These functions will ultimately only show a generalized message of success or failure. If you need to see in detail why a certain object is not converted, click `Window - Toggle System Console` and the plugin has more detailed output there.
+
+### Rename by Group
+
+Renames an object to an appropriate name based on its current grouping information.  
+This is often used when migrating original maps. Some Ballance-derived programs do not have a Virtools Group concept and therefore rely on names for grouping information.
+
+### Convert Name
+
+Switch between different naming standards.  
+Typically used to convert between different Ballance-derived programs.
+
+### Auto Grouping
+
+Auto-fill the grouping information for an object according to a given naming convention.  
+Note that the original grouping information will be overwritten.  
+If you follow certain naming conventions during the mapping process, this feature can do the grouping for you automatically.

 # Add Rail
 
-!!! info "Work in Progress"
+In the 3D view, click `Add - Rails` to expand the Add Rails menu. The menu is shown on the left side of the image below.
-    This part of manual still work in progress.
+
+![](../imgs/rail-adder.png)
+
+The right side of the picture above shows the interface for adding some rails, and we will introduce them in turn later, from top to bottom on the right side are: Add Rail Section, Add Straight Rail, Add Side Rail, Add Arc Rail, and Add Spiral Rail.
+
+!!! info "Rails with non-standard data"
+    BBP's rail adding menu is designed for new players to add rails quickly, and is not designed for skilled mapper to add rails. For cases where you need rails with non-standard data, such as rails with non-standard spacing or non-standard section, you need to build the rail section with Blender's own Circle operation, and then generate the entire rail with the Extrude, Bridge, or Spiral modifiers. In this way, you can control all the parameters of each step to meet your specific needs for rail parameters.
+
+!!! info "Source of the rail parameters"
+    The various parameters of rails used in the Rails Add menu are derived from actual in-game measurements and from the experience of several mappers in the Ballance community over more than a decade.
+
+    The rail section radius and gauge are derived from years of mapping experience and measurements. Side rail tilt degree data is calculated by BallanceBug. Mono and double rail transition sinking data from the calculation by Imbalanced Dream. Spiral rail spacing is measured from Level 9 and Level 13.
+
+## Rail Sections
+
+In the Add Rails menu, under the `Sections` category, you can add rail sections. A rail section is the outline of a rail, and the creation of a rail section is usually the first step in the creation of various types of shaped rails, e.g. rails made by lofting, extruding etc.
+
+### Rail Section
+
+To create a rail section, you can choose in the panel to create a mono or double rail section.
+
+When creating a mono rail section, the octagonal rail section is automatically created with the flat side edge facing up, while the double rail section is not (vertex tip facing up). If you need to change this behavior, you need to go into edit mode after creation and manually rotate the vertices of the rail section so that the flat side or vertex tip of the rail section faces up.
+
+### Transition Section
+
+The mono and double rail transition section will create a rail section that is suitable for mono and double rail transitions. This rail section is created without specifying any parameters.
+
+## Straight Rails
+
+In the Add Rails menu, under the `Straight Rails` category, you can add straight rails.
+
+### Straight Rail
+
+A Straight Rail is a straight rail of rail. To create a straight rail you need to specify a Length. You can also choose to create a straight double rail or a mono rail.
+
+When creating a mono rail, similar to a section, the flat side of the rail section is automatically turned upwards, and this behavior can be modified by entering edit mode after creation and then rotating.
+
+The creation of straight rails also supports the capping properties, which are controlled by the Start Cap and End Cap options located under Rail Cap, which are checked to cap the corresponding end. Capping is the process of automatically adding face for the end of a rail and correctly handling its normal. This is usually done to ensure that the rail is aesthetically pleasing where it comes into contact with other surfaces or objects, rail-to-rail joints do not need to be capped.
+
+### Transition Rail
+
+Mono and double transition rail can often be seen as an advanced use of Transition Section creation, where the section created by the transition section is extruded and the normals are taken care of to produce the result created by this option. To create a mono or double transition rail you need to specify a Length, which is also supported by the capping property.
+
+### Side Rail
+
+Side rails are created by specifying a Side Type which can be either Normal (for paper or wood balls) or Stone Specific (for stone ball specific). Side rails for paper and wood balls are the usual side rails that stone balls cannot pass through. Stone Specific side rails are side rails that are more tilted and can be passed by stone balls, and of course, paper and wood balls.
+
+In addition to the side rail type, side rail creation also requires the Length and capping attributes.
+
+## Curve Rails
+
+In the Add Rails menu, under the `Curve Rails` category, you can add curved rails.
+
+### Arc Rail
+
+The first thing you need to do with an arc rail is to specify the Angle and Radius, which indicates how much the rail will turn at what radius. Generally speaking, angles of 90, 180, and 270 degrees are more common, but any number of degrees can be specified. The radius is usually adjusted as needed. For the double rail arc, the radius is the distence between arc rail rotation center to the double rail section center. For the mono rail arc rail, is the distence between arc rail rotation center to the mono rail section center.
+
+Steps of the arc rail, the number of steps indicates the number of segments of the arc rail, the larger the number, the smoother the arc rail looks, relatively, the vertices will be more, the storage space and rendering requirements are also higher, so you need to choose a reasonable value.
+
+Arc rails also support double-rail mono-rail selection, you can create mono-rail arc rails and double-rail arc rails. The capping attribute is also supported.
+
+### Spiral Rail
+
+Spiral rail, or spiral double rail, is similar to arc rail in that you need to specify Radius, which is the radius of rotation, but not the angle, since it always rotates in 360 degrees.
+
+Spiral rails have an Iterations property, which indicates how many times the rail will spiral up, and a Screw property, which indicates the distance between each iteration.
+
+The spiral rail also needs to set the Steps property, which has the same meaning as the arc rail. However, it should be noted that the number of steps refers to the number of steps in each iteration, not the overall number of steps. Therefore, when adjusting the iteration attribute, you do not need to change the Steps attribute again.
+
+Side Spiral Rail also has a capping property.
+
+### Side Spiral Rail
+
+Side Spiral Rail, similar to spiral rail, but the ball is rolled along the side, similar to side rail.
+
+Side Spiral Rail does not have a Screw property, because Side Spiral Rail is designed so that adjacent spins share a common edge, so the screw is fixed.
+
+The Radius, Iterations and Steps attributes in the Side Spiral Rail settings have the same meaning as the spiral rail. Side Spiral Rail also have a capping attribute.

 # Report Issue
 
-!!! info "Work in Progress"
+## What Can Go Wrong
-    This part of manual still work in progress.
+
+BBP is not perfect, and since BBP's Virtools file import/export module is written in C++, BBP is more prone to errors than other plugins, and the consequences of errors can be more serious (including but not limited to memory leaks, accidental deletion of user files, etc.).
+
+In Blender, you will observe if the plugin execution goes wrong:
+
+* The expected effect is not achieved
+* A large stack of output text pops up at the mouse that you can't read
+* After opening the console using `Window - Toggle System Console`, you can observe the Python exception output.
+
+## What Part Went Wrong
+
+For the BBP plugin, if you observe something like `BMap operation failed` in the Python exception output, or the `IronPad.log` file in the `<Plugin-Install-Location>/PyBMap` folder, it means that The BBP plugin's BMap section, written in C++, is in error, and **you need to immediately save your current Blender document and exit Blender**. Because the plugin is in an abnormal state at this point, you should not continue any operations.
+
+If there is no such thing as the above, then this is just a normal Python code execution error and you don't need to worry too much about it, but the error is still fatal and it is recommended to exit Blender and report the error after doing all the necessary operations.
+
+## Where to Report
+
+If you have a GitHub account, you can create and report issues in [Issue page of BBP repository](https://github.com/yyc12345/BallanceBlenderHelper/issues).
+
+If you can't do that and you have proper way to contact with plugin author, then reporting directly to the plugin author is fine.
+
+## The Content of the Report
+
+First of all you need to describe in detail how you raise this error and what are the results of this error. If you can upload the documentation that led to the error, please try to do so (if it's not convenient to post it publicly, you can send it to the author through a private way such as email).
+
+You also need to provide the Python stack report output in the Blender console (use `Window - Toggle System Console` to open the console). If your error is an error in the BMap section, you also need to provide the `IronPad.log` and `IronPad.dmp` files in the `<Plugin-Install-Location>/PyBMap` folder to make it easier for developers to locate the error.

 # UV Mapping
 
-!!! info "Work in Progress"
+## Rail Mapping
-    This part of manual still work in progress.
+
+The menu `Ballance - Rail UV` in the 3D view provides the ability to map rails.
+
+To start mapping rails, you need to select the rails to be mapped (multiple selections are possible) and then click on this menu. Then you only need to select the material used for the rail. This will clear all materials for the selected object and assign all materials used on each face to the material you specify. Then you will set the UV of the selected object in the same way as the rails are post-processed in Ballance, so that the rails will have the same appearance as in the game by performing this operation.
+
+!!! info "Rails UV doesn't really matter"
+    In fact, all objects grouped in the `Phys_FloorRails` group undergo a post-processing when Ballance loads the level. What the post-processing method does is to reset the UVs of these objects according to a specific mapping function (`TT_ReflectionMapping` is called in Virtools). So the UVs of the rails don't really matter, because Ballance will set them uniformly for you when you enter the game, and even if you don't set any UV data to the rails, the rails will look correct when you enter the game.
+
+    Therefore, this feature is usually applied to set the UVs for objects that are not grouped in the `Phys_FloorRails` group, but you still want them to show the appearance of the rails material. Or for rendering Ballance map previews in Blender, etc.
+
+## Mapping Along Edges
+
+Mapping Along Edges is the most important feature of the BBP plugin, the most powerful and at the same time the most difficult to understand. It is widely used for setting UVs of custom structures or a line of floor, wood, etc. The menu `Ballance - Flatten UV` in the 3D view offers the Mapping Along Edges feature. It only works in **Edit Mode**, so you need to be in Edit Mode (and entering Face selection mode at the same time, since Mapping Along Edges operates on faces) to use it.
+
+Mapping Along Edges is usually used in combination with [Select Face Loops](https://docs.blender.org/manual/en/4.2/modeling/meshes/selecting/loops.html), [Shortest Path](https://docs.blender.org/manual/en/4.2/modeling/meshes/selecting/linked.html#bpy-ops-mesh-shortest-path-select) and other functions. You need to first select a series of faces, for example a series of consecutive Ballance floor sides, and then click `Ballance - Flatten UV` to start mapping along edges.
+
+The configuration screen for Mapping Along Edges is shown below, with Scale Size mode on the left and Ref. Point (refernece point) mode on the right, we'll explain the difference between these two modes later.
+
+![](../imgs/flatten-uv.png)
+
+Mapping Along Edges, as the name implies, means UV mapping along a certain edge. The specific operation is to use linear algebra to transform the 3D coordinates of the vertices under a new coordinate system using a transition matrix. In this new coordinate system:
+
+* The origin is the vertex with the index specified by the Reference Edge, as shown below. The figure below identifies the vertex index of the face in UV and 3D in yellow font, and the Reference Edge is 1 in the figure, then the vertex with the vertex index of 1 in the current face is used as the origin of the new coordinate system.
+* The Y-axis (i.e., the V-axis, XYZ corresponds to UVW, and will not be commented subsequently) is the line from the vertex specified by Reference Edge to the next vertex, i.e., the edge from vertex 1 to vertex 2, i.e., the edge with the serial number of 1, as shown in the following figure, which identifies the serial number of the edge of the face in purple font in the following figure in UV and 3D. Edge 1 is a vector that starts at vertex 1 and ends at vertex 2. It has a direction, is a vector, and needs to be normalized when used as a coordinate axis.
+* The Z-axis is obtained by cross-multiplying and normalizing the edge specified by Reference Edge (in this case, Edge 1) with its next neighboring edge (in this case, Edge 2). In the case of a three-point covariance where the cross-multiplication yields a zero vector, an attempt is made to use the normal data of the face instead.
+* The X-axis is obtained by cross-multiplying and normalizing the previously calculated Y-axis and Z-axis. The XYZ in the new coordinate system still needs to satisfy the requirements of the right-handed coordinate system.
+
+![](../imgs/flatten-uv-mechanism.png)
+
+After setting up the new coordinate system and building the transition matrix and transforming every vertex to the new coordinate system, we can discard the Z component and map XY to UV and mirror the vertices on the -U axis to the +U axis, which is why Flatten UV doesn't support concave polygons. The reason for mirroring is to prevent UV mapping errors, for example, in the above image, the upper edge stripe of the floor side mapping is located in the V-axis, if we flip the UV vertices in the above image along the V-axis (you can try it for better understanding), it will result in the final mapping display does not meet our expectation, i.e., the edges specified by Reference Edge do not show the floor side stripe.
+
+!!! info "Reference Edge actually refers to"
+    The Reference Edge actually refers to the index of the edge that needs to be mapped to the V-axis. Because this edge is directional, it also determines the origin in the new coordinate system.
+    
+    In short words, Flatten UV allows the user to specify an edge and then flatten it along the V-axis of the UV.
+
+After determining the coordinate system, we also need to know how far this UV mapping needs to be expanded, specifically what the scaling value of this UV mapping should be. For the V-axis direction, due to the Ballance mapping charcateristic (Ballance mapping always extend along the V-axis, and in Ballance, 5 in 3D is equivalent to 1 in UV), we can know the UV:3D relationship is 1:5. While for the U-axis direction, we can't determine it, that's the work of Scale Mode property, which lets the user decide the scaling of the U-axis direction.
+
+The Scale Size mode allows the user to directly specify the scale value, for example, the default value of 5 means that 5 in the 3D world is equal to 1 in the UV world, while the Ref. Point mode allows the user to specify the U value of the UV of a reference point in the surface, and lets the plugin calculate the scaling on the U-axis by itself. For example, if we switch the Scale Size mode in the image above to Ref. Point mode and specify Reference Point as 2 and Reference Point UV as 1 we can also apply the same texture, let's explain the principle here. First of all, Reference Point specifies the reference point, this reference point is relative to the vertex specified by Reference Edge, that is, the reference system origin of the offset, so here, Reference Edge is 1, Reference Point is 2, then the actual reference point for the vertex 3. Reference Point UV specifies a U value of 1 in the UV value of this point, i.e., it can be seen as forcing vertex 3 to be placed at a U-axis of 1. BBP will calculate the corresponding U-axis scaling value based on this point and apply it to all vertices.
+
+Scale Size mode is usually used for floor side mapping, since these faces have fixed U-axis scaling values. The Ref. Point mode is typically used for maps where the scaling value cannot be determined (usually due to model deformation that causes the scaling value to fluctuate around the standard range of scaling values), such as the upper surface of a sink floor generated from a curve with bevel shape, as shown in the following figure. We can be sure that the UV of the center of the sink floor must be 0.5, but it is not convenient to determine its scaling value because it is difficult to calculate it, so we just use the Ref. Point mode. The top half of the figure below shows the mapping result in the Ref. Point mode, and the bottom half is in the Scale Size mode. We can observe that in the Scale Size mode, the UV of the center of the sink floor is not exactly 0.5, which results in the center of the sink floor not being dark enough on the display. The Ref. Point mode, on the other hand, accurately sets the UV of the center of the sink floor to 0.5.
+
+![](../imgs/flatten-uv-scale-mode.png)
+
+Finally, Flatten Mode specifies the unfolding mode, Raw means that the connection between faces is not considered at all, and each face is treated as an independent content, Floor means that the continuity of adjacent faces in the V-axis direction is taken into account, and adjacent faces will be made adjacent in the UVs as much as possible, which can avoid the problem of visual duplications caused by Raw unfolding in the case of too many subdivisions of the road surface. Floor is often used in floor mapping, so it's called Floor. Wood is similar to Floor, except that it not only considers continuity on the V-axis, but also on the U-axis, which is often used in concave and convex wood mapping, and is the reason of its name.
+
+The figure below shows the distribution of UV mapping for three different unfolding modes. At the top is the Raw mode, where you can see that the Reference Edge of each face is expanded at the UV coordinates of the origin. In the middle is the Floor mode, where you can see that BBP unfolded a series of consecutive faces along the V-axis, instead of stacking them all at the origin as in the Raw mode. At the bottom is the Wood unfolding mode, which is unfolding a convex wood, and you can see that the continuity of the faces has been taken into account on both the V and U axes.
+
+![](../imgs/flatten-uv-flatten-mode.png)
+
+!!! info "Floor and Wood Flatten Mode failed"
+    Floor and Wood mode have more limitations than Raw modes, they only support rectangle faces, and they require a lot of modeling operations, usually only the geometry generated by batch operations (e.g. subdividing, lofting, etc.) will be correctly recognized by Floor and Wood.
+
+    If Floor and Wood unfolding modes fail and the resulting unfolded maps are completely unacceptable, try modeling in a more prescriptive way or switch to manual mapping.

 # Virtools Properties
 
-!!! info "Work in Progress"
+## Virtools Group
-    This part of manual still work in progress.
+
+The BBP plugin adds a new property to every Blender object, called Virtools Group. has the same functionality as Group in Virtools. Select an object and the `Virtools Group` panel can be found in the `Object` properties panel.
+
+![](../imgs/virtools-group.png)
+
+In the `Virtools Group` panel, you can click Add to group objects. After clicking the Add button, you can select Predefined and then select one of all legal Ballance group names to add. Or select Custom and enter the group name you want to add. The selected Virtools group can also be deleted by clicking the Delete button. Finally, all group data for this object can be deleted at once by clicking the Trash icon button (which will let you confirm before deleting).
+
+BBP also provides access to Virtools groups in Blender's other menus, see [Group Operation](./group-operations.md).
+
+## Virtools Material
+
+The plugin adds a new property to every Blender material, called Virtools Material, which bridges the gap between Virtools materials and Blender materials. Go to the `Material` properties panel and select a material to find the `Virtools Material` panel.
+
+![](../imgs/virtools-material.png)
+
+You can set material properties in the `Virtools Material` panel, just like in Virtools. All material parameters in the `Virtools Material` panel are maps of the material parameters in Virtools and will be accurately reflected in the final saved Virtools document.
+
+The `Virtools Material` panel provides a preset function, which can be started by clicking the `Preset` button at the top. The preset function allows the user to use some preset material settings, such as the material data for the top surface of the road, the sides, etc., for ease of use. Note that using a preset does not affect the material's texture options, and you will still need to set the material's texture manually once the preset has been applied.
+
+The `Virtools Material` panel also provides the ability to convert the material data in the `Virtools Material` panel to the Blender material for a visual effect in Blender. Click the `Apply` button at the top to perform this function. When you save a Virtools document in Blender, the material data in the Virtools document will be retrieved from the values specified in the `Virtools Material` panel and not from the Blender material. This means that a proper procedure for setting up a material is to edit the material parameters in the `Virtools Material` panel and then use the `Apply` button to convert them to the Blender material, instead of editing the Blender material directly.
+
+The `Virtools Material` panel provides material repair functionality, which is inherited from the [Ballance Virtools Plugin](https://github.com/yyc12345/BallanceVirtoolsHelper). The Material repair button is located to the right of the `Preset` button and the `Apply` button, and is a button with a wrench icon. Clicking it requires reconfirmation to prevent misuse. The material repair function determines which type of material the current material is based on the filename of the texture file it references, and then modifies the other parameters to make it visually appealing based on our preset repair settings (taken from the game). This is usually used for fixing objects that look like they have the wrong material in the game, such as a black Stopper, etc.
+
+!!! info "There is also a global material fix function"
+    In the 3D view, the menu `Ballance - Fix Material` is similar to the material fix function, but it will fix all materials within the current document. Don't use this feature unless you are sure that all materials in the current document need to be fixed, as it may set some of the originally special, correct materials back to generic values that you don't want.
+
+    The Global Material Repair function also needs to be reconfirmed after clicking on it before it can be used, to prevent misuse.
+
+The Texture property in the `Virtools Material` panel not only allows you to select a texture within a document by clicking on it, but also opens the Texture File Browser by clicking on the folder button on the right side, which allows you to select the texture you want directly from the file system (much faster than selecting it from the Shading tab). The file browser is navigated in Ballance's Texture directory by default, to make it easier to select Ballance materials.
+
+## Virtools Texture
+
+The BBP plugin adds a new property to all Blender textures (actually Images) called Virtools Texture, which creates a link between Virtools textures and Blender images.
+
+Unlike Blender materials, due to Blender's implementation there is no separate properties panel for textures, so we can only access Virtools texture properties in an indirect way in the `Virtools Material` panel. First find the `Virtools Material` panel by referring to the instructions in the `Virtools Material` chapter, then select a texture or open a texture in the material slot in the `Virtools Material` panel, and you'll see that the Virtools texture attributes are displayed additionally underneath the texture attributes of the material, as shown in the highlighted portion of the image below.
+
+![](../imgs/virtools-texture.png)
+
+Among them, Save Option indicates how the texture is stored in Virtools, and these are the common storage methods:
+
+* External: The file only stores the name of the referenced file. All Ballance native textures should use this mode.
+* Raw Data: The texture is stored inside the file, the disadvantage is that it will lead to a large file. All non-native Ballance maps should use this mode.
+* Use Global: Use global settings. We do not recommend using this unless you are modifying an existing map. We recommend explicitly specifying how individual textures are stored right here, rather than using global values. The global setting is determined when exporting the Virtools document.
+
+The Video Format indicates the rendering mode of the texture in Virtools, and these are the commonly used modes:
+
+* 32 Bits ARGB8888: The storage mode for all kinds of textures with transparency, such as the column gradient part.
+* 16 Bits ARGB1555: The way to store all kinds of maps without transparency, such as floor.
+
+## Virtools Mesh
+
+The BBP plugin adds a new property to all Blender meshes called Virtools Mesh. go to the `Data` properties panel to find the `Virtools Mesh` panel.
+
+![](../imgs/virtools-mesh.png)
+
+The Virtools Mesh is currently only used as a compatibility feature. It has only one property, Lit Mode, that can be set. Most early maps had black floor issue because they didn't know how to set the material correctly, so the Lit Mode was often set to Prelit to get the floor to show up properly. This attribute exists for compatibility with this compromise and the user usually does not need to set this option.
