Shattering glass in a frame

[Davers1]

Just place another surface test operator (referencing that frame object) below your PhysX Shape operator (adjust the distance you want), and link it to the event that just have PhysX Switch operator set to kinematic (so the glasses will stay frozen, but still other PhysX objects bounce on it).

EDIT:
It might be good idea also to add stop operator on that new event, apart from PhysX Switch), because they might inherit some velocities.

Oh, you star! That's just what I needed. Thanks!
