Hi, This is a bit of a weird one - but again, I only get the weird stuff happening From my understanding, if I'm in Room B and the door to Room A is sealed with an areaportal then I shouldn't be able to see anything in Room A unless I'm looking straight at it. Note: looking at it in mat_wireframe 3 areaporatl is open. The issue is I'm standiing in a room but I can see stuff (mostly models 98%) on the far side of the map even though the room is sealed. If I approach the areaportal then the displacements etc on the other side of it (in room A not the far side of the map) start to be renedered too. Any ideas why this would occur? Perhaps it's just a question of opening / closing the ap's as the cart passes over the nodes on the pathtrack < don't know if that would help. edit add on - does every stage of the map literally have to connect to each other?
