Hi all, I am trying to build a scenery with Ground2K4 (amongst others) which includes two projects a) the vicinity around the airport and b) an area at some distance from the airport. To build the Landclasses I have had to split this into two Ground2K4 projects, which generate BGLs into the same Scenery folder. This is where FS9 crashes. Any one have a clue how to get around this? B.
