Did you know that since dlc 2 gel will show up if you're using mat_fullbright 1?
It's true! (thank you horrible lit PTI map )

No don't say that, people might not compile lights in anymore!

Actually this is wonderful for testing.. mmm testing.

Anyone who uses this as an excuse to release a fullbright map will be promptly executed.

Cheers.

While I was creating the best map ever I came to the conclusion conversion gel isn't fixed

Hmm... Florescent Gel.
