Just to be clear..

Only way I can allow elements to intersect in a map is scenery? Right? Oh, and to double check, can scenery have open edges?

You can have elements intersect in the BSP, but it will most likely cause collision problems, and GBX models can have open edges, but there collision
can not

Faces can intersect, but cannot be in the same position at the same time.
