Anyone that knows how to map in hammer 4
 

This should be simple.

Just create a flat rectangle (in hammer 4) for a floor. Then just place a light_environment entity at the top of it and change the pitch to -60. Run it and tell me what you see. If it's black for all of you too then does anyone know if I need to do anything else besides just toss one of these in?

Why would this make black?

Agh: I just found my map lighting is causing a memory leak.

Fuck.
