Thanks to a pointer by Mike from TGC I was able to get Fog working. Until now I've only tried it through the Global Script settings, which doesn't seem to work at all. He suggested to try it in a script and after a while I did get.... FOG!!
It's very simple to get, I'll post two scripts here for Fog. Both of these scripts are related to a Trigger Zone. First set up a Trigger Zone and then attach the script to Main of the Trigger Zone.
The first one is a complete level always on Fog. Place the Trigger Zone were the Player Start Marker is located and you will have Fog in the complete level all the time (even when the payer isn'in the Zone anymore).
;Working Fog
;Header
desc = Activates Fog for a completete level.
;Triggers
:state=0,always:fog=1,fogred=255,foggreen=255,fogblue=30:state=0
This is a position dependant Fog. Place a Trigger Zone as large as you want, as soon as the player is in the Zone, Fog will appear. Once he's out of the Zone, Fog will dissappear.
;Working Fog
;Header
desc = Activates Fog when in Zone.
;Triggers
:state=0,plrwithinzone=1:fog=1,fogred=255,foggreen=255,fogblue=255:state=0
Put the code in a text editor, save them indepentantly as fpi files and attach them to a Trigger Zone and you've got Fog. Change the fogred=255,foggreen=255,fogblue=255 to any number between 0-255 to get different colored fog. 0 = none of the color, 255 all of that color.
fogred=255,foggreen=255,fogblue=255 = white Fog.
fogred=0,foggreen=0,fogblue=0 = Black Fog (doesn't work to well).
fogred=255,foggreen=0,fogblue=0 = Red Fog.
fogred=0,foggreen=255,fogblue=0 = Green Fog.
fogred=0,foggreen=0,fogblue=255 = Blue Fog.
fogred=255,foggreen=255,fogblue=30 = Yellow Fog.
fogred=120,foggreen=120,fogblue=120 = Grey Fog.
The rest you can figure out by yourself.
Once note: the Fog is quite far away, you need a large room or hallway or open space to really get the full effect of it. It works in an open space as long as you enclose it with walls to see the full effect of the fog.
