It makes more sence. Thanx Wade. I have only one question:

Maybye in two months I will start a new map :D
If you look in the Hoth sample map, you can find a portal.
I will look for it, and now it would be so easy...
Portal skies are the thing used in the Serious Sam engine. I really liked making map for that game.
They've also been used in Elite Force 2 to some superb effects...conversely they've been totally borked up in that game too.
