I have tried everything within my limited reach to fix this issue, however as I parent this body I imported as an fbx from Character Creator and an armature I got from DeepMotion with automatic weights, certain body parts (eyes, teeth, tongue etc.) get deformed and don't move in accordance with the rest of the body after I switch from rest position to pose position of the armature.
What I have tried so far: Parenting those body parts individually with automatic weights, rigging with Auto Rig Pro, merging the body meshes, weight painting (totally haphazardly since I have no clue how to do it right).
Blender file (before parenting the body and the armature): https://drive.google.com/file/d/1uI5m1pEl2IT64m0VF-qBSxtrlPDMmlbn/view?usp=sharing
How do I fix it? Any help would be appreciated. Thanks!
My guess is that there is no corresponding "bone" in the armature that I could connect those body parts to. However there has to be a solution?
