Hi Ed:
Instant Scenery "Labels" feature shows that Bill gave us a very nice challenge at
Outer Heron Island with those rocks he manually placed along the course of the airstrip (good thing I always keep collision detection "off" for my user aircraft !).
FYI: Those rocks are actually scenery library objects which can be excluded (or moved to the RWY edge) if desired.
Personally, I really like the rugged terrain at Bill's
00ME RWY-3 start location, and am happy with the airport CVX sloped flatten as displayed without any add-on terrain mesh loaded from 3rd parties nearby.
If, however, one sets FS Menu GUI terrain mesh resolution at a higher slider setting than 5 Meters (
ex: a setting of (2)
or even (1) Meters), one will have a nearly 2 foot "bump" near the
00ME RWY-3 start location.
BTW: I believe that Bill's scenery package size can be kept smaller- and his work-load for implementing a "fix" at
00ME might be made even easier- if he were to keep using his existing vector flatten data points in:
[FSX install path]\IBY_Herons_Nest\iBlueYonder\Heron's Nest\Scenery\cvx_2_herons-nest_CVX.bgl
...and modify that BGL by adding (1) more polygon to change its 'effective' FS run time loading priority by expanding its Geographic extent of coverage to that of a LOD-4 quad.
The alternative of making a terrain mesh BGL with multiple LODs that has a LOD 4-12 extent would dramatically add to the existing scenery package download and installed footprint size.
I also believe this would prevent end users from having to disable their add-on mesh just because of a (temporary) anomaly seen at
00ME with the current set of available BGL files for that add-on.
I did a test which used the existing
00ME airport sloped flatten CVX vector polygon vertices, and added (1) small 3-sided polygon with vertex altitudes of 64.5 Meters each at a location just NW of 45.00 North and 75.00 West Geographic coordinates (in the suburbs of Ottawa Canada !) at a LOD-4 quad distance from
00ME.
That "forces" FS to load the test CVX vector sloped flatten BGL at the same distance away as a add-on mesh that has
ex: LODs 4-12 extents ...because the Geographic extent of coverage for that CVX BGL now reaches all the way to Ottawa Canada.
This is a work-around for something Holger Sandmann previously reported, which is the tendency of FS to load a terrain mesh BGL with
ex: LODs 4-12 extents when one starts a flight
far away from an airport, and then having FS refuse to load any higher resolution terrain mesh and/or CVX vector "sloped" flatten BGLs that have smaller 'local-only' extents of Geographic coverage ...as one flies to the destination airport over a
larger terrain quad sized distance.

Many thanks again to Bill for sharing this great scenery with us !
PS: I'll be looking forward to acquiring
Nantucket ...as soon as it is ready.
