Fog question

[Limpet]

Ok I've read some posts about fog but nothing has helped me much so far.
My question, Is it possible to make fog appear in parts of your map but not in others.
Im making a css map that takes place mainly on city building's roofs, but players can also go down into the top most level inside most of the buildings. My maps is really a very big square where you can see from one side to the other, so Im trying to use fog to hide distances greater than the building you're on and clip the rest. This makes for some pretty thick fog, and as you may have guessed by now, is visible inside my buildings too. Also the buildings are pretty high up and I will be making fairly detailed streets below. The fog is supposed to cover that up as well. The height of my buildings are about 1024 units high.

Agian, is it possible to make fog appear only outside of my buildings?

As far as I know...no, you can't

But it's not something I've even attempted, besides once so...

Func_smokevolume, func_dustcloud, any of the other fog/smoke/dust entities.

But given the performance effect of using those, it isn't really realistic to do so.

Plus, you won't be able to attach any sort of occlusion or vis blockers to fog.

Ok, I'll work at it and see if I can get something to work.

Ok, Ive given up. I might just redesign bits of my map.
Bummer though, I spent a week trying to get the inside of one of the buildings looking nice.

Anyone ever figure out how to get the unrendered part to be covered in fog?
