I have a character model that has a jaw bone along with blend shapes for facial expressions. If I move/rotate the jaw bone, the face's mech goes with it: The mesh also has blend shapes. Here's the mouth opening via blend shape, without rotating the raw: This blend shape doesn't look great on its own, because it doesn't move the jaw/teeth. So, it seems I need to both move/rotate the jaw and adjust the blend shape. However, because moving the jaw also affects the mesh, it ends up kind of doubling how much the facial mesh gets moved: These blend shapes appear to be the default provided by Character Creator characters, so I don't think they were rigged "wrong". But I'm not sure how I can effective animate the character talking. I can't just move the jaw, since the lip sync software I'm using uses blend shapes. But I can't just use blend shapes, since the teeth with remain completely still. Does anyone have experience with rigged models using blend shapes as well as a jaw bone, and getting these to play nicely together?
