I decided that since we can add fs9 aircraft to the fsx demo why should'nt we try to add scenery, so I got the 79m mesh from simv installed it and found an afcad for an airport from the same area. The airport and the scenery mesh works because you can see the hills in the background. But what else needs added to add textures to the ground???

well at least we know addon mesh and afcads work ok.
edit: how many folders are in your fsx/scenery folder?...i've been adding lots and forget how mnay i started with :-/
Would I be right if I said 6??? Names:0303, Cities, Global, props, BASE and World
