Update on my map:
BSP should be pretty much completely final. All brushes have materials assigned now. I placed some important and less important static meshes around to get more of a sense what things will look like. This showed me that in some places the BSP needed a bit of editing to better accomodate the meshes.
There’s Heightfog in there, just quickly placed and tweaked to get a sense of things. I also did some fun tricks with the water, but I’ll talk about that later.
