My map is getting close to being done, so I decided that I'd start work on the detailing. The first thing I did was try to make a Skybox... It didn't go completely as planned. I followed [ame="http://forums.tf2maps.net/showthread.php?t=116"]this[/ame] guide, and I managed to screw it up... :facepalm: My 3D Skybox was going to be something simple, an extension of the water surrounding my map (it's an island, by the way) with some odds and ends floating around. To achieve the effect I was going for, I copied my water brush (the 1:16 one that was being used as reference), made it about three times as big, and deleted the original one from the Skybox. Currently, my 3D Skybox is nothing but a big water brush which I hope will simulate the appearance of an ocean. I copied my brushes, pasted them outside the 2D Skybox, shrank them down to 1:16 size, copied the mini-water brush, deleted everything else, pasted the mini-water brush, made it bigger, and put a Skybox brush around it. When I compiled and ran it, the water was invisible. It registered that there was water, but I could not see it. As a matter of fact, nothing that is fully submerged in the water shows up. Is there anything I could have forgotten to do that would have caused this?
