Shape Key List
You can look up the names and purposes of Menno's shape keys (885 in total). Use them as a reference when adjusting facial expressions or body proportions.
Usage
- Select the model in Unity's Inspector.
- Open the SkinnedMeshRenderer component.
- Adjust the slider for each shape key under "Blend Shapes" (0 = disabled, 100 = maximum).
Combine multiple shape keys to create custom expressions or body shapes.

This set enables more natural expression syncing. It controls the eyebrows (inner upper, outer upper, lower, etc.), eyes (up/down/left/right, blinking, squinting, etc.), cheeks (puffing, tightening, etc.), nose (wrinkling, etc.), jaw (open/close, forward/backward/left/right, etc.), and various mouth shapes. This may be changed in future updates.

Empty Shape Keys
Adding shape keys in the middle of a list in Unity can shift existing indices, causing preset values to mismatch. To prevent this, a number of empty shape keys (Empty) are pre-allocated, and new features are added to these slots during updates.
Fixing Expression Animations
Note
If you make significant changes to the eyes, mouth, or other features, default expression animations built on the original mesh may break (causing unnatural blinking, desynced lip-sync, etc.). In such cases, adjust the animation using the following steps.
- Select the root object of the Menno avatar.
- Assign
Menno_Layer_FX.controllerto the Animator component (contains default expression animation settings). - Open the Animation window via
Window > Animation > Animation. - Select the Menno avatar in the scene.
- Choose an existing expression animation in the Animation window.
- Click the keyframe for the modified shape key and edit its value.
- Verify the expression movement in VRChat Gesture Manager or similar tools, and make fine adjustments if needed.
