Building outside map, how to do a sky?

[liquidice]

Hey I want to do an outdoor map and I wanted to know how do I add a sky? (I'm new so go easy)_
Do I just make a huge roof like that of a building that covers the whole map, but then just sky caulk it and then texture it white?
plz help?

well since its an outside map i would make a ridiculously large box around ur map and texture the top of it ur sky texture. a warning: raidiant doesnt display sky textures they way they will in game sometimes. it may look like tile in radiant but in game it will look fine.

Here is a tutorial on making a skybox:
