I checked the Valve site, and I don't know what I'm doing wrong. I did the cube-mapping, I have a skybox, and I even used "cheap" water. All the sides of the brushes are nodraw except for the top. I tried making a new map just to try and make water, and it worked perfectly there. But when I try the exact same thing on my bigger map, it doesn't work. All it does is display the skybox. HELP!
