Requirements

Blender 2.79 or ii.fourscore or above (run as administrator is recommended)
- mmd_tools is not required! Cats comes pre-installed with it!
If you have custom Python installed which Blender might employ, you need to have Numpy installed

Installation

Download the plugin: Cats Blender Plugin
- Important: Do NOT extract the downloaded cipher! You will need the naught file during installation!
Install the addon in blender like so:
- This shows Blender two.79. In Blender 2.80+ go to Edit > Preferences > Add-ons. Also yous don't demand to save the user settings there.

Cheque your 3d view and there should be a new menu detail chosen CATS ....w00t
- Since Blender 2.80 the CATS tab is on the correct in the bill of fare that opens when pressing 'Due north'

Model

This tries to completely fix your model with 1 click.

Import/Export Model

Imports a model of the selected blazon with the optimal settings
Exports a model equally an .fbx with the optimal settings

Fix Model

Fixes your model automatically past:
- Reparenting basic
- Removing unnecessary bones
- Renaming and translating objects and bones
- Mixing weight paints
- Rotating the hips
- Joining meshes
- Removing rigidbodies, joints and bone groups
- Removing bone constraints
- Deleting unused vertex groups
- Using the right shading
- Making it compatible with Total Body Tracking
- Combining similar materials

Start Pose Way

Lets you test how basic volition move.

Pose to Shape Central

Saves your current pose every bit a new shape central.

Utilise every bit Rest Pose

Applies the current pose position as the new residue position. This saves the shape keys and repairs ones that were broken due to scaling

Model Options

Translation

Translate sure entities from any japanese to english language. This uses an internal dictionary and Google Interpret.

Split by material / loose parts / shapes

Separates a mesh by materials or loose parts or past whether or non the mesh is effected by a shape key

Bring together meshes

Joins all/selected meshes together

Merge Weights

Deletes the selected bones and adds their weight to their respective parents

Delete Zero Weight Bones

Cleans upwards the bones hierarchy, deleting all bones that don't straight affect any vertices

Delete Constraints

Removes constrains between bones causing specific bone movement as these are not used by VRChat

Recalculate Normals

Makes normals point within of the selected mesh
Don't utilise this on skillful looking meshes every bit this can screw them up

Flip Normals

Flips the direction of the faces' normals of the selected mesh.

Apply Transformations

Applies the position, rotation and scale to the armature and its meshes.

Remove Doubles

Merges duplicated faces and vertices of the selected meshes.

Custom Model Creation

This makes creating custom avatars a breeze!

Merge Armatures

Merges the selected armature into the selected base armature.
How to apply:
- Utilise "Fix Model" on both armatures
  - Select the armature you want to prepare in the listing above the Fix Model push
  - Ignore the "Bones are missing" warning if one of the armatures is incomplete (due east.g hair but)
  - If yous don't want to use "Ready Model" make sure that the armature follows the CATS bone structure (https://i.imgur.com/F5KEt0M.png)
  - DO Not delete any main basic past yourself! CATS will merge them and delete all unused bones later on
- Now you lot take ii options:
  - Only motion the mesh:
    - Uncheck the checkbox "Utilize Transforms"
    - Move the mesh (and simply the mesh!) of the merge armature to the desired position
      - You tin can use Move, Scale and Rotate
      - CATS will position the basic according to the mesh automatically
  - OR move the armature (and with it the mesh):
    - Bank check the checkbox "Apply Transforms"
    - Move the armature to the desired position
      - You can use Move, Calibration and Rotate
      - Make certain that both meshes and armatures are at their right positions as they will stay exactly like this
  - If you want to merge multiple objects from the same model it is often better to indistinguishable the armature for each of them and merge them individually
- Select the base of operations armature and the armature yous want to merge into the base of operations armature in the panel
- If CATS can't notice the os structure automatically: select a bone you want to attach the new armature to
  - Due east.g.: For a hair armature select "Head" as the bone
- Printing the "Merge Armatures" push button -> Done!

Attach Mesh to Armature

Attaches the selected mesh to the selected armature.
How to utilize:
- Move the mesh to the desired position
  - Yous tin can utilize Move, Scale and Rotate
  - INFO: The mesh volition simply be assigned to the selected bone
  - E.g.: A jacket won't work, because it requires multiple basic.
  - Due east.one thousand.: A ring on a finger works perfectly, because the band just needs one bone to movement with (the finger bone)
- Select the base armature and the mesh yous desire to adhere to the base of operations armature in the panel
- Select the bone you desire to adhere the mesh to in the panel
- Printing the "Adhere Mesh" button -> Done!

Decimation

Decimate your model automatically.

Smart Decimation

This will decimate all meshes while keeping every shapekey.

Salve Decimation

This will only decimate meshes with no shape keys.

Half Decimation

This will just decimate meshes with less than 4 shape keys as those are oft not used.

Full Decimation

This will decimate your whole model deleting all shape keys in the process.

Custom Decimation

This lets you choose the meshes and shape keys that should non be decimated.

Middle Tracking

Eye tracking is used to artificially rail someone when they come close to you. Information technology'south a good idea to cheque the eye movement in the testing tab afterward this operation to bank check the validity of the automatic eye tracking cosmos.

Disable Eye Blinking

Disables middle blinking. Useful if you just want eye motility.

Disable Eye Movement

Disables eye motility. Useful if y'all only desire blinking. Of import: Practise your decimation first if y'all check this!

Eye Motion Speed

Configure middle movement speed

Visemes (Lip Sync)

Mouth visemes are used to show more than realistic mouth move in-game when talking over the microphone. The script generates 15 shape keys from the 3 shape keys you lot specified. It uses the oral cavity visemes A, OH and CH to generate this output.

Bone parenting

Useful for Dynamic Basic where information technology is ideal to take one root bone full of kid basic. This works by checking all bones and trying to figure out if they can exist grouped together, which will announced in a list for you to choose from. After satisfied with the selection of this group you can then printing 'Parent basic' and the child basic will exist parented to a new bone named RootBone_xyz

To parent

List of bones that look like they could be parented together to a root bone. Select a group of basic from the list and press "Parent bones"

Refresh list

Clears the group bones list cache and rebuild it, useful if bones have changed or your model

Parent bones

Starts the parent procedure

Texture atlas

Texture atlas is the process of combining multiple textures into 1 to drastically reduce draw calls and therefore brand your model much more than performant

Create Atlas

Combines all selected materials into one texture. If no material listing is generated information technology volition combine all materials.

Generate Material List

Lists all materials of the current model and lets you select which ones you want to combine.

Useful Tips:

Split transparent and non-transparent textures into carve up atlases to avert transparency bug
Brand sure that the created textures are not likewise big, because Unity volition downscale them to 2048x2048. Dissever them across multiple atlases or reduce the individual texture sizes. This tin be easily washed in the MatCombiner tab.
Yous can tell Unity to use up to 8k textures. Do so by selecting the texture then choose a different Max Size and/or Compression in the inspector: https://i.imgur.com/o01T4Gb.png

Os merging

Lets you lot reduce overall bone count in a group gear up of basic. This works by checking all bones and trying to figure out if they tin exist grouped together, which volition appear in a list for yous to choose from. After satisfied with the pick of this group you can then set a percentage value how much basic you would similar to merge together in itself and press 'Merge bones'

Refresh listing

Clears the group basic list cache and rebuild it, useful if bones accept changed or your model

Merge bones

Starts the merge process

Bake

This is a not-subversive way to instantly produce a optimized/Quest variant of (almost) any avatar!

For more data please visit the Bake Panel Wiki Page.

Shape Primal

Apply Shape Key as Basis

Applies the selected shape key as the new Basis and creates a reverted shape key from the selected one.

Settings and Updates

This plugin has an auto updater. It checks for a new version automatically once every day.
