I have looked at all the articles I could find and cannot find out how to make a sky box. I read the article in the Valve developer community and it read this…
Adding sky to a map
Simply texture a world brush (not a brush entity) with the tools/toolsskybox material. (|Ok did this.|)
In-game, the skybox will be seen through each surface that toolsskybox is applied to.
toolsskybox Brushes do not need to be box-shaped
My questions are, do I make the box go around the playing area and hollow it out? Do I leave it as a box just sitting there? Should it automatically just surround the map? Plz Help.
