View source for Sky List

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.

|-
| <code>d1_trainstation</code> || [[City 17]] before the teleporter accident
|-
| <code>d1_canals</code> || [[Route Kanal]] & [[Water Hazard]]
|-
| <code>d1_eli</code> || [[Black Mesa East]]
|-
