I added some exactportals to my map, The exportation was fine... but now when I open Sapien, it renders the whole map which it cause some triangles to dissapear. I opened my bsp tag on guerilla, and everything seems fine, guerilla says the bsp has portals.

What I want to do is to make my bsp like bloodgulch, if you see when you enter into the bases the outside area is not being rendered until you go out. I want to make the same effect with my map, but I dont know why is not working
