I was testing out different skys on my map to see whether a day time or night time setting would be better. So I went here to get the sky names: https://developer.valvesoftware.com/wiki/Team_Fortress_2_Sky_List When I compiled the map and tested it.The sky was there but water and reflective textures were reflecting black and purple textures, they still had their base textures though. I compiled again with Vrad off and testing out all of the sky names. looking at the compile log, only sky_hydro_01 and sky_badlands_01 works. Is this some sort of sky discrimination?
