there is sequence where my objective is to shatter a glass pane...but the shards do not disperse, they collide with the collision object but dont go any further than a few units, and then they just hover there.

the shards are active rigid bodies; each on its own collision layer(0-14)

the colliding object is a sphere, an active rigid body; with passive keys set and also its own collision layer (-1)

everytime i run the sim...i get nothing but collision and interpenetrating errors...

...any help would be greatly appreciated.
