Urbane_Guerrilla: Cloth wrinkle is all about the gravity. First thing you have to find is where the body is protruding. The cloth will either hang from or be pulled by those points. Next thing is if the cloth is being moved or pulled somehow. The wrinkles will follow the direction of the pulling and line up with it, or radiate, in a narrow angle and swooped into curves, from that point.
dunno lol
