I'm making a photoreal version of KYIP (Willow Run) for fs9, and am very pleased with it so far. (The FS9 default runway's actually line up pretty well with the photos I'm using.)
The issue is this:
From certain angles, all looks well...
But from others, I get the default ground textures showing through some runways and aprons...
I've noticed this in a few other sceneries that use photoreal textures too. Elevation issue?
