Here is my really gross looking conference room. But the lighting isnt correct here, i have 2 roof static mesh actors (i basically cloned the room and knocked out the middle walls and then joined the room) and the lighting is not uniform, its making some surfaces appear darker than the should be. i dont really want to scale the entire room because i found out materials just stretch onto a static mesh actor, while on a BSP brush the materials themselves can be scaled. I have not been able to find a work around yet.(I found some of the above out in the official documentation.)
edit, here is a better picture to point out lighting issues
