This is my first attempt at rigging, so bear with me. I have read numerous posts, and a great deal of the book "Mastering Maya 8.5". But I have not found the answer to this question.

I have created a monster and I want to rig it so that, among other things, the lower jaw opens and closes. My first attempt didn't have sufficient bones in the rest of the skull to prevent parts of the skin from participating in the jaw movement which I did not want to move. Adding a few more bones, specifically in the upper jaw, seemed to solve most of the problem.

But now, when I open the lower jaw, all the teeth elongate! In a weird sort of way this makes sense, I haven't told Maya that the teeth are supposed to move intact with the jaw, but I don't know how to do that. How does one designate that certain parts of a skin are ridged and are not deformed even when the entire section of the skin to which they are attached is deforming?

Thanks in advance!
