Fog..

[JK-47]

I've never worked with fog before, so I need to know how to get it to show up.
I took a wild guess and went into the sky tag, and filled in the nulled area of the fog, with the fog that I PMI'd. Is this right?
It's not really showing up at all, though.

Playing with some of the distances and colors for fog in the sky tag should do the trick. Especially the opaque distance. Of course that kind of thing is really like working with a clipping plane and not proper fog.

Yep, what he said. 'Real' fog is used in the water on the Silent Cartographer and on the floor of Chillout, for example. Editing the sky tag usually gives good results though.
