Anyone who has tried to export DEM Earth in the past, will have come across this problem, which was tricky to solve. Maxon has some inbuilt tools, but they really kinda suck. We needed an elegant, intelligent solution to this problem. The solution is the GeoReference Tag. it has the ability to re-project UVW coordinates, to flat mapping in realtime. A unique, and clever solution, to an old problem.
The following video shows how it is now possible to use the GeoReference Tag, to re-project uvw coordinates, to match flat mapping. All this needs is that for you to insert a GeoReference tag into the hierarchy, and link that tag, to a specific texture. You won't be able to tell any difference, which is pretty much the perfect solution. Now your uvw coordinates are re-projecting, in realtime. When you export, or make editable, your textures will be where you expect them to be, and that particular problem is nicely solved.
