whenever i put anything reflective in the map, it has that black and purple stuff that means that something somewhere hates me. i have a cubemap, at head height, and there’s an env_sun and a light_environment entity on the map. this also effects water, to see what i mean, go on my server, 184.108.40.206:27017 and look at the roof of the house in the middle of the map (i am currently afk, working on my walls (IRL)).
P.S. sorry for posting a TF2 problem, but i figure this is the best place to get help mapping.
