Good afternoon,
I wanted to make an inquiry. I have to make expressions. I have to modify each of the parameters? Or is there a way to simplify it? Otherwise, it should modify the 16 parameters of the mouth and 21 angles of the face T_T
For the mouth.

head turns linked to the mouth
Comments
I'm sure there are many ways to go about rigging the mouth to the head. My approach is to have one warp for the head X and Y as the parent of all of my mouth form/open warps.
The reflect motion may prove useful as well.
