For Precipice, most of my exterior stuff has no portals whatsoever, because it's fairly low-poly. However, my interiors have a lot more detail. My big problem has been my bases- optimized, each one has 20,690 faces. That's right, all in one room. 17,000 of those are on one wall. And you wonder why I've been struggling to get that room working right. However, now all I have to do is tweak the portals in red base to fix one very small problem, and then all the portals are done, thank god. Then I can move on to fixing glitches like the flag animations, figuring out why the spartan laser fix didn't work as planned, and tweaking spawn points and weapon spawn times. The end is near.

Oh yeah, and I still want to do custom lightmaps. Might as well go all out on this thing.
Okay thanks. I think this advice will become greatly in handy, since one of my maps is completely an interior and the other has a part of the a30 BSP interior (2nd part by the cliff), which is beyond an astronomical amount of faces.
