but... are texture size and number of lights really relevant for the compile time of visibility?
(btw.. it is still calculating the same portal as mentioned above..)

The map is fairly complicated... so i can understand that it will take time, but there is still 12 000 portals, so the time should depend on that, shouldn't it? An 5h for one portal is weird.. this is really irritating.. because the map gets really heavy if i don't calculate it. And every other part of the entire game is finished -_-...
