Thanks for the info :) Okay so I make a skullcap, I make the hair groups, then I descide that the cap needs just a little tweeking to get an area right. I pull it into 3DMax, move some things around and bring it back into Poser... What happens to the relationship between the original hair growths and the new skullcap? Is that broken basicly making it so a person has to start over in the hair growth aspect, or will they still apply as before?
