Howdy Fibber;
Unfortunatly there was an issue with many of the ground (Aircraft Parking Pads, Tarmacs, etc) poly's floating up covering any object (Hangars, Aircraft, etc.) place on them in CFS2. It stemed from having polys layered over top of the background poly. Never have resolved the issue which was a real shame. There method produced very crisp looking results. In the future I may have another crack at it but right now I'm working on getting my GMax skills back up to par.
