Todo: Update Brightness/Ambience value to match 20th anniversary update, while keeping the old one from Orange Box/pre-20th anniversary release.
This is a list of Half-Life 2 skies, 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:For HDR-capable games, you need to add _hdr to the end of 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').
These skyboxes are available to Half-Life 2 and most games and mods using Source 2013, the Orange Box branch, and earlier branches.
Note:Newer or standalone games, such as the Left 4 Dead series, Portal 2, or Counter-Strike: Global Offensive do not ship with, nor using base HL2 content, and as such may not necessarily include these skyboxes. The skybox VTFs and VMTs from HL2 can be used in any Source engine game, however.
HDR versions of all skyboxes except sky_borealis01
and sky_wasteland02
are available by appending _hdr
to the sky name. HDR skyboxes is only available with Source 2007 ( )/Source 2009 (PC) and later.
Note:While Source 2006 does support HDR, all Half-Life 2 default skyboxes (except Lost Coast) on this branch does not support HDR at all.
The table below explains the prefixes used in map filenames.
Only outdoor maps that have both skyboxes and light_environment
s are referenced by this list.
