I've run into a few problems with a simulation i'm running, I have a couple of active Sphere's constrained using springs which in turn are constrained to a passive Sphere, this is then parented to a characters hip (it's meant to be a piece of metal chain that hangs to the characters side) i've then created a tube which covers my chracters thigh & parented it to the thigh bone, I then made the tube a passive body. The plan was to use this tube to stop the chain going though the charaters leg, but when i run the simulation the active Sphere's interpenetrate the tube. Does anybody know of any tips or tricks to help solve this interpenetration??
Any help would be cool, thanks.
