Simple VRChat Unity Helper Scripts

A collection of simple Unity scripts to automate tedious tasks for creating VRChat Avatars.

These scripts are not failsafe and don't check for possible errors. Use at your own risk.

Source control/Backup your projects before running any of these

Requirements

• The VRChat SDK must be imported

Note

The tools can be found in the "Tools" menu in Unity

Copy / Paste Blendshapes as JSON

Copies / Pastes the selected GameObjects skinned mesh renderers blendshapes between avatars

Apply Clothes

Applies the Parent Constraint Component to a cloth item.
The cloth items Armature bones must have the same hierarchy and must contain the actual bone name in its own name

• Avatar
  • Armature
    • Hips
      • Spine
  • Clothes
    • Armature
      • FancySocks_Hips (will parent to Armature/Hips)
        • FancySocks_Spine (will parent to Armature/Hips/Spine)

Create item toggle

Creates an item toggle for the selected item.

It will

• Add the parameter to the VRC Parameter list
• Create Animation Clips with On/Off state
• Add the parameter to the FX Controller
• Create a layer in the FX Controller with the correct states and transitions

The toggle in the menu itself has to be created manually

Fix single key frame animations

Searches all animation clips and add a second keyframe if they only have one.
This used to be necessary for VRChat and might be no longer needed.

Set up facetracking

Basic setup to automatically create animations for face tracking to be used with VRCFT Standalone based on a template matching VRCFT Parameters and model blendshapes

At the top of the file is a template for a lip tracking setup for the Rexouium

It will

• Add the parameter to the VRC Parameter list
• Create Animation Clips for each blendshape specified
• Add the parameter to the FX Controller
• Create a layer in the FX Controller with a blendtree

Examples

new TrackingSetup("JawOpen") {
    Single = "MouthOpen"
}

Will create the JawOpen parameter and create a 1D blendtree animating the MouthOpen blendshape from 0 to 1.

new TrackingSetup("JawX") {
    Left = "JawLeft",
    Right = "JawRight"
}

Will create the JawX parameter and create a 1D blendtree animating the JawLeft blendshape from -1 to 0 and the JawRight blendshape from 0 to 1
A neutral state with an animation clip with both blendshapes being 0 will be between them.

new TrackingSetup("TongueX", "TongueY") {
    Top = "TongueUp",
    TopRight = "TongueUpRight",
    Right = "TongueRight",
    BottomRight = "TongueDownRight",
    Bottom = "TongueDown",
    BottomLeft = "TongueDownLeft",
    Left = "TongueLeft",
    TopLeft = "TongueUpLeft"
}

Will create the TongueX and TongueY parameter and create a 2D blendtree animating the given blendshapes based on their position.

The properties are based on the position on a 2D blendtree

Batch upload avatars (SDK 3.3.0 or newer)

Uploads all selected avatars in one go.
They must have been already uploaded at least once and have a valid blueprint id attached.
