Today I discovered hdr and color correction; also can someone please tell me why every rounded wall isn't lightning properly.
This looks much better. Get rid of those sprites on the fluorescent lights though, it just looks ridiculous. Your round stuff probably needs smoothing groups (I keep meaning to write a thing on how to use these because there's no guide at all, but I am not convinced I fully understand them myself). And ever since Steve pointed it out, your differently sized stairs are hurting me physically in real life.
