I'm used to doing this in xchange...I have the bones in CC4 but I'm flummxed on how to add them/link them to expressions.
Any help is appreciated!

This is something I would like to know too, So far it seems like to do animation with non human characters, like werewolves, monsters, trolls, talking animals, etc
We have to learn to use blender or something else instead of Iclone for that type of animation,

I imported a Sonic character from sketch fab that I rigged the body in CC4. That works but no facial expressions or bone mapping.

See 3:41 in this video for adjusting the facial bones in the Expression Editor:

Thanks.  What a pain....exchange was better for setting that up...aw well.
