Shooting through the floor with Destructibles

I’m trying to do this:

Or something similar.

I have my destructible mesh settings working fine with the object standing up as a wall. When I rotate the object and shoot, however, it either completely falls (gravity, duh), or it doesn’t collide, or it floats away. Weird.

Any way to get this right?

Try enabling the World Support flag along with using a support depth of 1 so that the chunks hold together until they receive enough damage to break free. I would also make sure that you’ve set some of the chunks so that they can not receive damage so that you can shoot out a hole along the chunks you wish.
