I don't think the Collision physics or Physical reactions are actually treated as solid,
I don't know about any one else, but any physical response on my PC seams ' weak ', EG If an actor is colliding with another and another actor bumps the first actor, the first actor can fall through the other physical object.
An example, If you set the collision multiplier below 1.0 the object will hit it then fall throw, It also breaks with other settings as well.
I think this might be a situated with possibly my graphics, but this is a concern I'd like addressed before i buy such amazing software.
