How to fix xbody shrek face 006

I'll take the mouth sliders as an opportunity to explain one thing: left double clicking the icon reset ALL the correspontend sliders, even the ones you deliberately changed. In Mari's case, I did some tweaks. If that's your case, just drag the sliders on the extreme left to center. That fix the problem. If you didn't do any changes, just reset them all. But you are wasting an opportunity of further detailing you model. These new sliders have great potential!
