Pretty
much every level needs one and I'll show you how to
use them.
Firstly
you need to have the area where the sky will be and
then load up the skies texture set.
Find the
texture called toxicskytim_dm3
and draw out the brush where the sky will be, don't
worry about the sky texture looking the way it does
in the editor, it won't look like that in the game.
This sky
texture has it's shader information set so it'll
will emit some light and it also has a sun value set
so it will create some neat shadows
As you
can see from this shot the sun is lighting up some
of the walls but not the others.
Some of
the sky textures are broke!, a few don't move so you
won't get a realistic effect and some of them don't
even show up :)
The best
thing for you to do is to try each one out until you
find one that suits your level best.
