I've been finding lately that when I pose V4 her lower jaw does funny things like sticking out from the chin. If I move it from where it sticks out and then zero out the dial, the lower jaw disappears or goes back to where it belongs. If I don't do anything, it will show up on a finished rendered image. Is there something to keep it from happening? If I make the lower jaw "invisible" V4 can't smile :)
