# SWBF-msh-Blender-IO # SWBF-msh-Blender-Export
.msh (SWBF toolchain version) Import-Exporter for Blender WIP .msh (SWBF toolchain version) exporter for Blender 2.8
Currently capable of exporting the active scene without skinning information.
### Installing ### Installing
You install it like any other Blender addon, if you already know how to do that then great! Else head over [here](https://docs.blender.org/manual/en/3.0/editors/preferences/addons.html#installing-add-ons) to learn how to do it in Blender 3.0. You install it like any other Blender addon, if you already know how to do that then great! Grab the [latest release](https://github.com/SleepKiller/SWBF-msh-Blender-Export/releases/latest) (or if you're the adventerous type [clone from source](https://github.com/SleepKiller/SWBF-msh-Blender-Export/archive/master.zip)) and you'll be good to go.
However if you don't know how to install then read on!
These instructions are going to be for Windows. If you're on a different platform I'm sure some quick web searching can help provide you with answers.
First download and extract the addon [latest release](https://github.com/SleepKiller/SWBF-msh-Blender-Export/releases/latest).
Then open up Explorer and paste `%USERPROFILE%\AppData\Roaming\Blender Foundation\Blender\2.80\` into it's address bar. Then go into the `scripts` folder in that directory and copy the `addons` folder from the extracted addon into the scripts folder.
Next open up Blender, go into Edit > Preferences > Addons. Select "Community" tab and then search for ".msh". "Import-Export: SWBF .msh export" should come up, check the box next to it. The preferences window should look like this once you're done.
![Installed addon.](docs/images/blender_addon_installed.png)
If you've done that then the addon is installed and you should now find "SWBF msh" listed under Blender's export options.
### Reference Manual ### Reference Manual
Included in the repository is a [Reference Manual](https://github.com/SleepKiller/SWBF-msh-Blender-Export/blob/master/docs/reference_manual.md#reference-manual) of sorts. There is no need to read through it before using the addon but anytime you have a question about how something works or why an export failed it should hopefully have the answers.

### Work to be done ### Work to be done
- [ ] Investigate and add support for exporting bones and vertex weights.
- [ ] Investigate and add support for exporting animations.
- [ ] Investigate and add support for editing and exporting SWBF2 cloth. - [ ] Investigate and add support for editing and exporting SWBF2 cloth.
- [ ] Implement .msh importing. Currently you can use the 1.2 release of [swbf-unmunge](releases/tag/v1.2.0) to save out munged models to glTF 2.0 files if you need to open a model in Blender.

The `reload_package` function from \_\_init\_\_.py. Before writing this I had barely touched Python and when I saw that glTF-Blender-IO had a function to assist script reloading "I thought that's useful, I think I kinda need that and I don't know how to write something like that myself yet.". And it was very useful, so thank you to all the glTF-Blender-IO developers and contributors. The `reload_package` function from \_\_init\_\_.py.

## Importer
This plugin can import one or more .msh files as well as .zaabin files. .msh files can be imported as models or animations.
### Import Properties
#### Import Animation(s)
If you wish to import animation data from one or more .msh files or a single .zaabin file, check this box. This will only work so long as you have preselected an Armature! The imported animations will then be added to the Armature as Actions. If an Action with the same name already exists, the importer will replace it.
### Import Failures

#### "struct.error: unpack requires a buffer of x bytes"

### Import Behaviour to Know About
#### Deleted skeleton meshes
If the .msh model to be imported has nodes with meshes that are weighted to or animated, the mesh data on that node will be lost upon import. This is because nodes that are weighted to or animated must be converted to bones in an armature, and bones in an armature cannot be meshes. Eventually we will add functionality to preserve the mesh as a specially named child object of the relevant armature bone.
#### Normals and vertex colors
Normals and vertex colors are currently not imported. Normals will be calculated by Blender.

### Materials Operators
#### Fill SWBF Properties
Fills in SWBF properties of each material used by all selected objects. This operator will only work with materials that have ```Use Nodes``` enabled and will just fill in the Diffuse Map property with the name of the image used by the material's Principled BSDF node.
It is used by selecting the relevant objects and choosing `SWBF` > `Fill SWBF Material Properties` in the `Object Context` menu:
<img src="https://raw.githubusercontent.com/SleepKiller/SWBF-msh-Blender-IO/master/docs/images/mat_fill_op.png" width="400" height="400"/>
#### Generate SWBF Nodes
Generates shader nodes that attempt to emulate the SWBF properties of a selected material. Call this operator by clicking the `Generate Nodes` button found at the bottom of the selected material's SWBF properties panel. Only transparency settings and diffuse texture mapping are currently supported. When importing a .msh file, this operator is automatically called on each material extracted from the file.
You must click the `Generate Nodes` button every time you edit the material properties and wish to see the results. The generated nodes will not automatically update when the SWBF properties are changed.
It is not necessary to call this operator for materials to correctly export.
## Skeletons and Skinning
This guide assumes you have working knowledge of Blender Armatures and deformation with vertex groups, as well as how to create, edit, pose, and keyframe bones in an Armature.
### XSI vs Blender
XSI has a very free-form take on skeletons and skinning. Models can be skinned to other models in a rather arbitrary manner, whereas in Blender, a model can only be skinned if it is parented to an armature and can only skin to bones in that armature.
Moreover, Zero Editor requires that skinned models be parents of their skeletons, which directly contradicts the structure Blender mandates! The exporter works around this by reparenting skinned objects to their armature's parent, and reparenting the root bones of the armature to the skin object. Note in the examples below that the armature's bones are not technically part of the scene's object hierarchy in Blender, as they belong to the armature object itself.
### Example Skin Hierarchy
Upon export, skinned objects are reparented to the armature's parent, and the armature skeleton reparented to the main skinned object:
#### Blender
* dummyroot
* Armature
* bone_root
* bone_one
* bone_two
* skinned_obj
* sv_skinned_obj
* skinned_obj_lowrez
#### Exported
* dummyroot
* skinned_obj
* bone_root
* bone_one
* bone_two
* sv_skinned_obj
* skinned_obj_lowrez
### Example Bone Parent Hierarchy
The same goes for objects that are children of an armature, but are parented directly to bones in that armature, as could be the case in a simple door:
#### Blender
* dummyroot
* Armature
* bone_doorleft
* bone_doorright
* left_door_mesh (bone parent: bone_doorleft)
* right_door_mesh (bone parent: bone_doorright)
#### Exported
* dummyroot
* bone_doorleft
* left_door_mesh
* bone_doorright
* right_door_mesh
### Skeleton Notes
1. Animated msh bones can have have geometry. To accomplish this, create a bone in the scene's armature and a mesh object with the same name as the bone. Parent the mesh object to the bone and make sure their origins are equal. When exported, the bone and the mesh object will be merged into one. The inverse process occurs when importing bones with geometry.
### Skinning Notes
Skinning/vertex-weighting in Blender is a very complex topic, these docs will focus solely on your considerations for exporting a SWBF compatible skin.
1. .msh files can weight a vertex to a maximum of 4 bones. When painting weights, ensure each vertex is meaningfully influenced by a maximum of 4 bones. It won't break the exporter if you exceed 4, but the 4 largest weights per-vertex will be kept and renormalized, and the others will be discarded. It is also worth mentioning however that SWBF2 (PC) only appears to supports 1 weight per vertex, despite the toolchain accepting and processing .msh files with more weights.
2. An object will be exported as a skin if it is parented to an armature and has vertex groups. The skeleton will be reparented to the skin object which is not named as a collision or LOD object.
3. As is the case with exporting in XSI, make sure you apply transforms on your skinned objects before exporting!
## Animation
This guide assumes you know how Armatures work, and how to switch between, create, and edit Actions in Blender.
### Actions and Animations
This exporter can convert Actions used by Armatures to animations compatible with SWBF's toolchain. If an armature is found among the objects to be exported, the exporter can include the armature's currently set Action as an animation in the .msh file. As of now, animation via Armature is the only way to export Blender Actions.
When exporting an Action, all frames between and including the first and last *keyframes* of the Action will be included. For example, if the first and last keyframes are 0 and 5, the exporter will record bone positions at frames 0, 1, 2, 3, 4, and 5, regardless of how many frames are actually keyed. Don't worry about using as few keyframes as possible to save a smaller animation as the exporter will record bone positions and rotations for each frame.
If you have armature bones that are weighted to by a skinned object, but you do not wish for them to be exported as part of the animated skeleton, don't keyframe them. The exported animation will only include bones that are explicitly keyframed at least once in the Action.
### Animation notes:
1. If exporting an animation, your exported .msh file's name should be that of the animation/action itself.
2. Bone constraints are not exported.
3. Don't include multiple armatures in one export!
4. Blender's animation speed defaults to 24 fps. If you want to see exactly how your animation will play ingame, set it to 29.97 in the `Output Properties` section of the `Properties` editor.
