I'm trying to put a helmet on some P5 hair. I'm thinking it should mat down and stick out from the bottom. I used the classical hair and scaled the helmet up. Over 10 frames I then scaled the helmet down over the hair. I pushed the calculate dynamics button. The hair doesn't seem to interact with the helmet at all. Both the hair and the helmet have collision detection on. Am I just dreaming or should this work? (using P5/SR-2)

If this won't work I was thinking of making some P4 hair into a cloth object and see if it would push between the head and helmet.

Any suggestions appreciated.
