collision offset and collision depth... a real peice of cloth has two sides (inside and outside) and thickness. a cloth mech is composed of polygons, which mathematically have zero thickness. the collision depth and collision offset dials emulate thickness by 'extruding' the cloth inwards by the amount of collision depth units and outward by the amount of collision offset units. thus, the cloth now has a thickness of collision offset + collision depth. any specified collision object intersecting this volume will be treated as a collision. collision offset determines the distance between a cloth object and a collision object at which the collision detection begins. collision depth determines how close the cloth object must be to a collision object in order for a collision to take place. increasing this value will increase the distance at which the cloth and collision object will collide.
