First off, is there a way to tell TF2 to take JPG screenshots by default instead of TGA? I thought I saw that somewhere, but I can't find it. The real question is, what to do about these ugly pink checkers that are showing up on four of my surfaces. An image is attached. I've got cubemaps all over, I've run buildcubemaps in-game and restarted the map, I don't get the checkers on any other surfaces (I was getting them before the cubemap step). I even connected these faces to the nearest env_cubemap, reran buildcubemaps, restarted the map. Nothing. Anyone know what's going on?
