Activate/deactivate fog Area

[DRedshot]

You might have to use particle effects instead of fog, unless you can attach a boxlight to the fog, much like you can attach one to a billboard, if you can do that, it will work

1. attach fog to boxlight,
2. move boxlight away from map,
3. use SetLightColorTo or whatever the function name is to fade light to 0,
4. fog will be same colour as boxlight!
