Ok, I'm making a character for an animation, and I finished modeling her. I made a few blend shapes for facial animation, but I've run into some issues now. I keep getting 2 problems when trying different things.

First, using the setup exactly as I have it, everything works fine. She does all of the blends. But, her tteth don't move to the right place in the base model like they do in the targets. The teeth are seperate geometry, but parented under the head geometry.

Next, after trying to combine the head and teeth into 1 piece of geometry, the blend shapes work perfectly, teeth and all. But now, the base head is translating over to each corresponding target head whenever I use the sliders.

What can I do to remedy this? I can't think of anything else to do. Any suggestions? Any help will be greatly appreciated!
