Unfortunately, I then discovered that the vendors do not approve the use of UTX in P3D. That's something I may have chosen to ignore at home for my own use but not something for a reputable museum to do so, having raided the Curator's simulator budget again, installed what I thought would be a reasonable alternative - ORBX England - but I've come across a problem. As you can see from the screenshot below, only the taxiways, runways and aprons are showing - the hangars and the base grass texture are missing. And to add insult to injury, some thoughtless person has built a house on the runway and planted trees in equally inconvenient places!


I tried raising the level of the airfield in the scenery.cfg to a position above the ORBX scenery and this is the result:

The hangars and runways are back and the house and trees are gone but it's now sitting on a very odd texture base complete with water features.
I'm very rusty at this sort of thing - the last time I had any thing to do with Flight Sim was setting up the sim in FS9 3 years ago - so I've probably missed something very basic but any help to get the airfield looking like it does in the top picture would be gratefully received.
