I need some help sorting out this issue. I'm using Xplane 11 and your scenery LSZH V2 (excellent scenery btw, congratulations!). I'm also an ortho4xp user.
I want to use ortho scenery for the surrounding area of the airport, so, based on info I got on some thread, I moved the the ini entry in the end (Aerosoft LSZH Airport Zurich V2.0 c), right above zzz_hd_global_scenery3.
I can see the ortho scenery around, great, a few small issues have risen with some parts of the airport and some assets not touching the ground but ok, I'm ok with it. It's minimal.
