Blendshape Animation Creator

Unity Editor tool for creating and editing static facial-expression AnimationClips from a SkinnedMeshRenderer without changing the source avatar or prefab.

Requirements

• Unity 2022.3
• No VRChat SDK dependency

Open the tool

Open Mekabu > Blendshape Animator.

Basic workflow

1. Drag an avatar root into Avatar Root.
2. The tool selects a SkinnedMeshRenderer named Body automatically. You can replace it using Face Renderer.
3. Create a new .anim asset or drag an existing standalone AnimationClip into Editing Clip.
4. Adjust blendshape values while checking the isolated preview.
5. Enable the blendshapes that should be written and press Apply Blendshapes to Clip.

Only blendshape curves for the selected renderer are replaced. Other curves in the AnimationClip are preserved.

Preview controls

• Left drag: rotate
• Right drag: pan
• Mouse wheel: zoom
• Face / Full: switch framing
• Reset View: reset the preview camera
