Problems with facial animation

I’m working on a project for the 10 Second Club (my first), and I’m having a bit of a problem. I have set up the phonemes, and have actually gotten a pretty good looking and realistic sentence form from the model. The problem I’m getting is that some of the phonemes are going into the negative and causing a deformation of the model, which in turn, causes the lips to close on themselves. Its really messy looking. Am I missing something or doing something wrong?

Are you talking about Lipsync and RVK’s?

Check out “Edit Your First RVK” or somesuch halfway thru and then “Final Tweaking”.
