"...because the map overlay does not hug or form to the editor terrain like a decal – it is a ‘flat’ image,..." (from engine-driver site)
I'm not so sure of this statement. I've explored my route, to several location, and consistently see the 'Overlay' floating (not hugging) the
curvature of the terrain more than 80/90% of the time. Admittedly, in cases of extreme terrain changes, within small areas, peaks of terrain do poke through the overlay.
Viewing the sim above and below the Overlay seems to confirm this observation... the following pics of a house lined, hillside location, in a rural community.
In another region, I found a 4 meter (+/-) space between the floating Overlay and the terrain. Altering the terrain, up or down, to the level of the Overlay seemed to have no effect or change to the Overlay. I suspect that the overlay, is in fact, following some form of topographical data, but I don't know that. It's just what I'm seeing in the route.
