Sorry, no funny image to post, nothing to see,I just tried to drop a mannequin as a rigid object onto a trampoline (dynamic cloth plane with constrained corners) in live simulation, it fell, bounced, then disappeared from the camera view, all well and good. Calculate the sim, something might have been a bit too bouncey, at frame 30 the mannequin showed
-2147483648 degrees x,y,z rotation and -1.#IND0000 x,y,z translation

Hmmm, back to the drawing board...
