{{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 {{hl2|1}} skies, along with pictures of each skybox. The {{Ent|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 {{Command|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'''').}}
<onlyinclude>
These skyboxes are available to {{hl2|2}} and most games and mods using {{src13|2}}, the {{orangebox|2}}, and earlier branches. {{note|Newer or standalone games, such as the {{l4dseries|2}}, {{portal2|2}}, or {{csgo|2}} 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 {{code|sky_borealis01}} and {{code|sky_wasteland02}} are available by appending {{code|_hdr}} to the sky name. HDR skyboxes is only available with {{src07|1}} ({{360}} {{ps3}})/{{src09|1}} ({{PC|1}}) and later.
{{Note|While {{src06|3}} does support HDR, all Half-Life 2 default skyboxes (except Lost Coast) on this branch does not support HDR at all.}}
