I'll try not to be confusing here...
each bone in the face has a stretchy setup using lookat constraints and point helpers, one at each connection. So for instance, the stretchy control at the corner of the mouth is parented into a point helper that is parented to another point helper that shares the same orientation. This point helper, at the top of the hierarchy, is directly linked into the head bone, but is sharing a position constraint between the head bone and a the jaw bone. This is so that when I rotate the jaw open, the corner of the mouth will always stay between the top and bottom lips, but by grabbing the child of this point helper I can still move the corner of the mouth independently, and because the parent is linked right into the head bone it should follow the head when he looks around. Now, this set up makes sense to me and I don't understand why it's not working. when I rotate the head around, the corner of his mouth seems to drag behind.
If anyone understands what I'm talking about and has some idea please help. I'm using Max 2011
