Alright, thanks ;D.
Was planning on using something like that to make a lower jaw for inhuman faces (MLP, Kystal, etc), as the upper part of the face could be easily done as a hair or mod headpiece, since it wouldn't have to move. Just needed a way to have the lower jaw move properly when breathing or interacting with the penis.
:-\Now I Just have to figure out how to make a mod properly.
