I exported one of avatar from CC4 with Motion(idle animation) + Mesh for Unity(2021.3), and built materials via CC4 Importer(1.6.3).
When I used the animation exported with the avatar, the avatar looks fine. However avatar mouth gets open when I used Mixamo animations as the image. Other animation package I purchased in Unity asset store has the same issue on the mouth of CC4 avatar.

  1. Is this a known issue?
  2. How to fix it?

I’m new to CC4 here, but have watched the tutorials.

There are two things you might try:

  1. first is from the Convai tutorial, which says to find your “Avatar” and “Configure” it (button) - then select the Head, then select the Jaw Bone, and set it’s transform to “None”.
  2. Another is to ensure you didn’t check the “Mouth Open as Morph” from CC4 Advanced Export options.
  3. And finally (also from Convai tutorial), from the Unity “Animations” window, find all Mixamo animation curves that are applied to “Skinned Mesh Renderer” and delete those.

Here is a link to the Convai tutorial with this advice happening about 6+ minutes into it.

I’m guessing you’ve either moved on, or found this solution already.

So I’m posting this for the potential to help others later on.
