When ever I try compile my map, I either get a lit map with poor FPS, or a fullbright map with good FPS. Either VRAD. Most of the time if I try both I end up with the fullbright version. I have tried compiling with VRAD and VVIS set to all 4 combinations (Both normal, both fast, VVIS fast/VRAD normal, VVIS normal/VRAD fast.) Doing Alt+P only complains of 'No Player Start' but I have spawn rooms in place so that should not matter, plus I don't think the lack of a player start would change things here. I am using a custom skybox texture (this one specifically) but that appears fine with lights or not. I also tried to compile with the standard sky_tf2_04 it defaults to, but that didn't work either. I have run the compile log though the log checker, but in case you want it I'll post it at the bottom. I can't figure out why I can't essentially get both VVIS and VRAD to work at the same time. Could someone shed some light on this situation or how I might go about fixing it? Many thanks in advance.
