Okay, I'm adding a 2D skybox to my map. My map is fairly large already and I'm only 15% of the way done. My map will have a 3D skybox to come, but I need a 2D skybox for testing. (No skybox can really mess up your HUD, scripts, height, that stuff.)
But when I create a skybox around my map and hollow it (A large box around my map, I know it's lazy but creating individual faces around each exterior brush would take HOURS.), it doesn't show up in-game. I'm using sky_day_01_09 (night map). This bug is recurring, and also makes compiling times up to 30 minutes.
Anyone know the problem?
