hey, thanks for the reply. i just like the idea of having it driven by dynamics, but i think you're right. i'll try animating by hand. seems pretty straight forward.
on another note, do you know a way to add facial rigging to a mixamo rig? i have a workaround which involves attaching another head (with pose morphs) and hiding the original head. it works but obviously, it's not very elegant. is it possible to un-bind, add the joints / point clusters / controllers and then re-bind the whole thing?
thanks, again!
