Many thanks for your great feedback!
This gives me the motivation, to implement some more small or middle airports.
First steps with AC3D are very hard, making a lot of mistakes, producing a) nothing. b) large holes in the ground or c) just small holes in the ground:
Converting single-objects on a non-flat mesh with more than one texture may look like this (even making a flat airport-ground,
the mesh remains not flat):
After this first "making of LSGN", I think I got it now, more or less!
So, I hope to do my next upload till begin of September.
First, I also will be on holiday for the next two weeks.
@Trespassers: I’m looking forward for your update of LSGY Yverdon! If it doesn’t work with 3DSMax, maybe it can be done using AC3D . Good Luck!
