Yeah, that's because I have a few Garage style doors around the map, seeing as they wouldn't be able to carry those big heavy wooden crates and books down to the main storage area through the narrow stairs coming up from the Stack.
And yeah, been working on optimization. Settled all the physics props to save server processing, as well as used the hint/skip stuff to get a consistent average of ~100 FPS in all the rooms, including the main hallway, which always crapped out to 40FPS in the Beta 1.x version of the map.
As for the caves area, it's pretty much the same area as it was in the old version of the map, except for tweaks in the lighting so that it isn't eye-rapeingly bright in HDR mode. Any ideas for what to do with this area appearance-wise?
