Personally I prefer Scotflight to ORBX Scotland. There is now a version of Scotflight designed to sit atop ORBX Scotland that might improve things for you.

 

For the ultimate Scottish scenery though, you can't beat Horizon's VFR X although it is expensive and huge! Vol 8 Scotland South and Vol 7 Scotland Central are £20 each!

 

Hi will Horizons VFR X work on top of Ftx Scotland

No, because they're at the same "level"; Horizon VFR X is photographic scenery textures, that means it's aerial photography accurately placed in the simulator (plus mesh and coastlines). Those photographic textures have to sit above FTX Scotland's textures (and associated autogen) which means you could only see FTX's airports.

 see this thread as it could also be caused by having scenery library ordering issues:

but, it sounds like the OP might also have the corrupted terrain.cfg bug

i had the same thing with trees all over my runways and weird out of place textures

 

the method for fixing is on the orbx forums here (need to sign in to read it)
