List of skies

This is a list of skies available in the Steam caches, along with pictures of each skybox. The light_environment settings listed (Ideal Sun Angle, Ideal Brightness, etc) are recommendations based on settings used in official maps; other values may also be appropriate. To test skies in singleplayer without recompiling the map, bring up the console and enter sv_skyname <sky_name>. Quicksave the game, load it again and the old skybox should be temporarily replaced with the new one.
