Adding a Sky to a map?

I haven't seen a tutorial about this anywhere, can anyone give me the skinny on how to add a sky to a map?

Use the enviroment trigger action - set sky.

For something so simple, I didn't think anyone needed a tutorial. :bgrun:

Damn i could have sworn i looked through the Envirornment actions. Thanks.

You're not nessicarily forced to use that trigger.. if you don't need the sky for a map to change mid-game, you can always use Map Options - Sky.. ^^

.. I've found that when you set it in editor preferences it has no effect on the map when you run it, only when you use the editor, so you have to use the trigger...
