That was an experiment I did with the texture set from Sock's website. Made some models with Gmax, hacked up a few I found on the internet to reduce poly count. At the time all it could ever be was one room. Vis time was prohibitive, so the map is unvised.
Then TyrUtils showed up. In the second shot you can see what I turned into func_detail. Vis treats it as just a box. Vis in under 2 minutes!!!
The unvised version with texures and sound is here
