You're welcome, Adrian - pleased it's of use. Apparently it's been embedded on a couple of other forums, too, so I hope I don't end up getting any flak for it from JF or the devs!
Anyway, for those who don't have time to watch the video, I took some snapshots from within FSX.
This is with JF's Real Scenery and the UK2K UK VFR Airfields, Gerry Winskill's UK Farmstrips and all the sliders pushed to the right in the scenery options:
Note the lack of 3D objects to start with
The objects do seem to 'pop up' out of the ground as I fly along - but once they are in place, it looks quite reasonable from the cockpit (i.e. without zooming)
On this next one, you can see some trees generated in a small lake or large pond. I guess it could be flooding, though!
In another picture that I can't seem to find now, there were a collection of such large ponds and the trees where very well placed around them - so I guess it's swings & roundabouts.
I will take a couple of a city such as London a bit later (that is covered in the video - just jump to the last 1/4 of it) and stick them up. They look more impressive from a distance than they do close up. I've not tested the night lighting effect as yet, due to having another package installed for that purpose.
