Hi,
I have some questions about regions(A8-Com):

As i can not disable a region manually(pro only :(), under which circumstances does the engine clip them?

Does it save some clipping time when the Engine frustrum-culls a Region, or is this already mostly compensated by ABT?

In other engines it is possible to have a region only visible, when you are inside the region or looking from another specified region through a portal into the region.

Is such a setup possible too?
Let's say i have a room in a manually created Level. This room has only one Door. The region has the size of the room.

Is it possible that the region is only visible when i am in the region or looking through the doorframe?(manually disabling it, is quite handy here, but not possible -.-)
