After adding face tracking shapes, you might notice that the mesh for mouth_OFF, mouth_flat, and mouth_flat_lipsync_OFF is lower than it should be.
This is intended and not a bug. Set the blendshape -----FT----- to 100, and the shapes will become normal. The animator will set -----FT----- to 100, so you normally wouldn't notice the issue.
The shapes are modified to prevent meshes from protruding when you open your jaw. The mesh is hidden in Kipfel's face, and the shape is synchronized for each mouth morph. The original resting position is too low, causing the mesh to become larger and protrude from the face when the jaw is opened. To fix this problem, I adjusted the resting position of the meshes, and correspondingly, the blendshapes need to be adjusted.

Kipfel's default FX layer states are all set to WriteDefault off. The face tracking controller I provide is designed to work with WriteDefault on/off universally.
You may notice that Kipfel cannot trigger MMD expressions in most MMD Worlds when dancing. This is because Kipfel's FX WriteDefault settings are incompatible with MMD World. If you need MMD expressions, the simplest fix is to change all states in Kipfel's FX to WriteDefault on.
After changing all states in Kipfel's FX to WriteDefault on, please check Match Avatar Write Default in MA Merge Animator component under Eye Tracking and Lip Tracking GameObject.
<aside>
⚠️ If your FX remains WriteDefault off, do not check Match Avatat Write Default.

If MMD expressions still cannot be triggered, please ensure all states within FX are set to WriteDefault on.
You need to change all states in Kipfel's FX to have Write Defaults on.
