This lighting bug applies to Id's Q3A maps as well, so it's likely a driver issue. Ah well, next time it's BETA list 1st ;]
In particular, the lighting was so bad in the upper corridors, that I didn't know I was walking toward the invisibility until a split second before I heard the narrator call it out "Invisibility!" Max-brightness = ugly, washed out textures and completely destroys the atmosphere of the map- I wish authors would find this and fix it by at least giving it a limited beta-test phase.
The note about the shaders- for example, where the +100 health powerup is, you can walk up to that window, and the gold reflection becomes opaque, and VERY bright.
And what's with those swiveling hand things?
