I am going to the store today to check on an article I was looking at yesterday that deals with hair in Poser 5, so I will get it and see if it helps. Don't know about collision detection, didn't get a chance to read it through yesterday, but I will let you know what it says about the hair room. Can't remember the name of the mag, have to go see the covers...lol Don't get old...heh Marque
