Hi. I try to rig an open mouth.
The corners of the mouth are not sharp, they are rounded.
My current Idea looks like this. (Simplified to a 2d side line drawing of an open mouth. Look Attachment)
If you run animation, you will see that the mouth opens and closes in a line.
After frame 75, the mouth is moved, the mouth corners are deformed.
(- edit … bone roll issue. corrected. Now it closes without side move -)
The mouth should close in a line. If you move it, it should keep its shape.
I would be glad if you have an idea how to solve this.
Thank you for your attention.
