A project I have not worked on in a few years. I had some help earlier trying to use the UFO to build a few race courses for my motorcycle sim. Mark of Lake of Constance hangar had started his epic repo of famous motorcycle race courses was a big help. Australia has two classic motoGP courses. The most spectacular one is on Phillip Island, South of Melbourne.
I presently have a partial .btg with a lake, helipad, and most of the racetrack, but the Land classes for the track are taxiways and are far too flat as what makes PIGP so challenging is it's gradients, it is built onto the contours of the little shallow arroyo it occupies, which makes it one of the most exciting courses to ride. The .btg was generated as an airport so it removed most of the surrounding land contours. So can someone who's done some small airfield generation possibly crop out the track and leave the small lake and heliport, and leave the area around the helicopter port and lake with their contours intact?
I can make the rest of the racetrack, I already have an .ac that is mostly finished except for some buildings and trees.
