2 Terrain questions

My first question is if there is any way to make fog regions. I want a red fog in one region and a green fog in another, but I can't find any way to do it. Unless I made it so whenever a unit went into the red area the fog would be red and when they went into the green area it would be green...but it's a multiplayer map so I don't think that would work too well.
Ok, second question. I've seen all those fancy terrain pics that look really cool, but how do you make it look like shafts of light are coming down through the trees? Thanks for the help, hopefully these things are actually possible =P.

Ya if it is multiplayer you probably wouldnt want to do that cause it would look weird. You can only use the low weather fog that is near the ground. Make a region and set it a weather effect.

I am not sure about the shafts of lights, there aren't usually any tricks. Just use rays of sunlight as a weather effect.

I didn't even notice that ray of light in there =D. I didn't think it would be under weather so I didn't even check. By the low weather fog do you mean the Dungeon blue, green, red and white fog under Create Weather Effect?

Ya, that is the only fog that you could put in regions.
