FogArea Activation? HELP!

[Mackiiboy]

How can I use FogAreas to activate on a callback??

I want a FogArea to activate on a callback, but it's there even before I enter the script area. It's deactivated in the editor but still there ingame.

.
I am pretty sure that the global fog is the only fog you can enable or disable in game (if I'm wrong, please correct me).
If it's possible for you to use fog-particle systems instead of fog-areas, you should try that instead - particle systems are at least create- and destroyable.
