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 360-degree panoramas 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.pngNote:For HDR-capable games, the _hdr prefix must be added to the end of the sky name (excluding Episode One skyboxes) to prevent texture stretching.

These skyboxes are available to Half-Life 2 Half-Life 2 and most games and mods using Source 2013 Source 2013, the Orange Box branch Orange Box branch, and earlier branches.

Note.pngNote:Newer or standalone games, such as the Left 4 Dead seriesLeft 4 Dead series Left 4 Dead series, Portal 2 Portal 2, or Counter-Strike: Global Offensive Counter-Strike: Global Offensive do not ship with nor use 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 are only available with Source 2007 (Xbox 360 PlayStation 3)/Source 2009 (PC) and later.

Note.pngNote:While Source 2004 (since Day of Defeat: Source/Half-Life 2: Lost Coast engine update) and Source 2006 does support HDR, no default Half-Life 2 skybox (except Lost Coast) on this branch is HDR capable.


The table below explains the prefixes used in map filenames.

d1_canals Route Kanal & Water Hazard
d1_eli Black Mesa East

d2_coast Highway 17, Sandtraps

background Menu Background Maps

Only outdoor maps that have both skyboxes and light_environments are referenced by this list.

Note.pngNote:For clarity purposes, the skybox examples shown here have been stitched together in the style of an HDRI texture seen in modern engines. Source does not support HDRI textures.
