Hi Convai Team,

I’m experiencing an issue with my character’s jaw movement. The lip-sync is working perfectly, but the teeth do not appear to be moving along with the jaw.

Have you encountered anything similar before, or could you advise on what might be causing this issue?

My avatar was created in CC4 (Reallusion) and I have added all the target meshes as shown in the screenshot below.

Thank you for your help.

I’m not fully sure I understand the issue.

Are you saying that the lipsync is working, but the jaw itself is not moving, or that the jaw moves but the teeth do not follow the jaw movement?

Could you please share a short video showing the issue? That would help us understand the problem more clearly.

Hi @K3

Correct, the lip sync is working fine and the jaw itself moves correctly. However, it seems that the teeth do not follow the jaw movement.

I’m sharing a short video below to help you better understand the issue.

Thanks!
