Been working through the theory of using bones to move features on a face. The good news is it turns out a few guys have used this technique for animating facial expressions within Max and have produced some really cool (and wonderfully intricate rigs). I started with a test using the ponytail bone to drive the chin of a character. It was a good feeling being able to push that chin around within Antics. It is encouraging me to continue the tests. One problem was that the pose was lost once the character was directed to do something else, like walk. So I'll need to sort this.
At the very least facial expressions for static poses are looking good at this point.....
