Hi shavedferret, Normally, objects can "pass through" each other. When collision detection is turned on, objects CAN NOT pass through each other. Objects must not be touching each other when collision is turned on. Collision must be turned on for each object involved ... AND ... for the Poser studio. If collision is turned on when the objects are already touching, the objects will be locked in their position. cheers, dr geep ;=]
Remember ... "With Poser, all things are possible, and poseable!"
cheers,
dr geep ... :o]
