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 suggestions 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.
Note: If you are mapping for Half-life 2: Episode 2, you need to add _hdr to the end of most sky names (Excluding Episode 1 skies), if it is not already there so it does not cause the Sky Texture to stretch. (So, if your sky name was sky_day01_01, you would make it sky_day01_01_hdr').
source materials.gcf
These skyboxes are available to Half-Life 2 and all games and mods using the Source Engine.
These skies are HDR capable if mapping for Half-Life 2: Episode 2.
The table below explains the prefixes used in map filenames.
Only outdoor maps that have both skyboxes and light_environments are referenced by this list.
