Darken a spisific spot on a map?
For instance, there are some caves, and I want them to be dark and gloomy.
or... an underground building, the interior of which I want darker then the rest of the map.

Edit Heres an example:

The building will eventually be moved underground but I want to find a way to darken its area before I do

actually i was wondering the same thing

i think there's a documentation about it...yeah there is BF2_lighting.doc

i haven't read it and it looks really complicated but it probably has what you're lookin for

Yea, I've toyed with that, and it makes it darker, but I want it DARK, really really dark.
Did I mention I tried a shadowregion? that seemed to have no effect.

You could just make the whole map dark and use omni light to make the rest of the area light again.
