First, you I daresay you moved her too fast. 10 frames is a third of a second, and in that time she is rotating 90 degrees and moving vertically. Look at the hair that isn't tangled; is that not the sweep effect you get when someone with longer hair falls, or bends over and snaps upright quickly? And I would bet that the swept hair was on the top and sides of the skull. The hair on the back of the skull was trapped between the collision surface of the skull and the force of the rotation and translation over such a short time. Once that happened, your guide hairs would be colliding with themselves and the skull....and any that wrapped around and penetrated between polygons in another group would freeze that simulation at that point. Dnyamics of any kind have to be given time to settle into a starting position, and the denser the collision fields, the more time is needed. I usually -start- at 30 frames to settle, and have wound up having to go to 120 frames in one case before the sim settled out.

The quick and easy location of the collision flag is on the dial controls. Just select the item or body part, click on the 'properties' tab on the dials, and click on the collision detection box you find there.

 

Yeah i was not thinking how fast 10 frames actually is in an animation. I had finally found where the collision checkboxes are and I have been playing around with some simulations and renders and I think I am getting better at this but I also think I want to find a way to get the hair on a skullcap type thing.

I think I will have to increase the dynamic simulation time if only to allow the hair time enough to settle down and stop moving around like it does.

Thanks for your input. I had the cloth room down pretty well there for a while but then I never used it there for  about a year or two so its almost like starting over on both of these. Though I am better with the cloth room lol the hair room always kicked my ass.
