I can use Unreal Editor 3 fine. I can make a map, I can even build the map. What I cannot do is build the map with extra textures loaded. I checked the windows page file in the task manager performance tab while I tried this once. It seems every time the page file hits 2.25 gb the processor stops running the program. This normally happens when static lighting is being built. I tried increasing the page file size, but that didn't work. I was wondering if anyone else has been having this problem or knows how to fix it.
