What's with the hair passing right through the skull every time she moves her head?  Did you forget collisions, or have them turned off on purpose for some reason?

PS:  I'd like to see this with Poser hair collisions turned on, because I heard a rumor that it's near impossible to keep Poser's dynamic hair from jittering and acting up when collisions are enabled.  For example, with collisions on, have the girl shake her head, then stand still for a few seconds.  Poser's dynamic hair will continue to dance about nervously much longer than it should, and look quite unnatural.  Unlike other hair engines in such apps as Lightwave, Maya, 3dsmax, etc., it's near impossible to calm this effect in Poser.

Or is this rumor incorrect?
