katahu: ops, sorry i didnt knew it. now i think its all ok
skynoz: thanks, so then its done in gmax and exported to the game as if it was a building or anything like this? great, im new to fs editing but i have experience in 3dsmax, so it will be easier
but, correct me if im wrong, with gmax i make all the "visual" part, but I still need to make the taxiways, parkings, etc in afcad (the "logical" part of it, i mean, to let fs know where is everything)?
sorry im completely newbie to all this :-)
