It's not really for building a room from scratch. It's more like the Crysis editor...you make a building in 3D World Studio, 3ds max (it doesn't matter what), and load it in the editor and place it. There's no lightmapping to worry about, so there's no reason BSP geometry is needed.
You can still use 3D World Studio if you want to, but there is no difference between loading a building from that or 3ds max.
The lighting changes the workflow a bit...just think of everything as a regular mesh, just like you would do if you didn't have any lighting at all.
