Sup guys. So I took the map 2fort5r.bsp and created a new one with different (and arguably better) lighting than the original. The 5+ minute video below is a lengthy one demoing me do this.

If you want to skip to the important parts, than at the ~1:25 mark, I run the BSP file through my own map viewer, and you can see me toggle back and forth between the lightmaps only and lightmaps plus textures. At the ~2:35 mark you can see me pull it up in FTE Quakeworld and walk around in it.
I apologize for the potato quality (it took me over 2 hours just to upload this video). I will email OMC the map so he can make it available to everyone interested.
