I am trying to upload a custom character. My eyeballs do not synch. My rig has the head bone with two eyeball bones. Anything I can do to fix the eyes better.
Can you please provide your custom character so that we can take a look?
Here also is our Custom Character FAQ for you to review: https://blog.deepmotion.com/2020/11/19/animate-3d-custom-characters/
Sure here is the fbx and blender file for it.
