A Tool Texture used to place skyboxes. Applied to a brush to represent the sky. The actual texture shown during play is controlled by the map properties setting "Enviroment Map (cl_skyname)". The default is desert. Custom skies are normally added to the gfx/env/ folder and then selected in the map properties before compiling. You can find all the sky names that come with HL by looking in the gfx/env/ folder (for legacy WON installations, you will find them inside the pak0.pak file which you can open with any software that is capable of reading Quake PAKs files like PAKScape).

SKY textures must be applied to visible faces while the rest can be textured with NULL.

Weather and Counter-Strike: Condition Zero - Deleted Scenes

If you are mapping for Counter-Strike: Condition Zero - Deleted Scenes and you use any entity related to weather, the SKY texture MUST be applied to all faces of the brush, so select "treat as one", when applying SKY textures.

If weather entities aren't working, that might be the reason.

This notice might also applies to other games/mods that control weather.
Sky texture applied to brushes is treated differently during rendering. It does not generate extra wpoly's as normal texture does. Some tutorials tell you that it is good idea to use sky texture as a filler for large unseen areas, I have no evidence that this is a good method of reducing r_speeds, when the hint and skip textures are available.

Correction: the "treat as one" in Hammer Editor's texture application tool is not intended to apply a texture on all the faces of a brush at one time. Instead, use SHIFT+click to select all faces and CTRL' to select multiple objects.

Me: When you have a custom GoldSrc skybox, is there any reason to include BMP files? Are they used anymore? Or just the TGAs?
Admer: Yeah, software mode I think
func_cambreaKable: software mode uses tga's too though
func_cambreaKable: i have only tga skyboxes in WAR and they work on software mode
Mikko: software mode falls back to tgas if bmps can't be found
Mikko: bmps can be used by gl too if you have an old graphics card that supports those paletted texture extensions
