How could I do this? and only for a section of the map?

However, before you transition in and after you transition out, you'll be able to see into the area which is foggy. A potential solution for this might be to make a foggy particle system which you enable while the player is not in the fog zone.

Just use an env_fog_controller with small near and far values, and transition into it when you enter that part of the map.

I tried using that with a brush entity (func_fogvolume? Something like that), setting near to 100, far to 160, and colours to black and "25 25 25" , but it didn't work when triggered. Also, the z-clipping section of that entity applied even when it was disabled.

Any ideas? :S

The brush entity doesn't work AFAIK. You have to use env_fog_controller.

aaaah, ok. I'll try the entity on it's own then. any way to fade in the fog, rather than have it instant?

Yes, I believe there are transition parameters on the fog controller.

any idea where? I can't see it :S

Interpolate time doesn't seem to be it
