I've created a body suit for my character, it took me a while to understand what i was doing, i'll try and explain it as best i can: the grouping tool is your best friend! using the grouping tool you will have to select individual body parts> select new group> add all> assign material> and then create a name for it like "leather" or "suit" and make sure it is spelled right each time you add a new body part. i've spent hours redoing the entire body just because of a lack of focus. This process will take around an hour, but it is the only way i know of, take your time with it. I hope this helps a little, Morgan
