I guess we both agree that a renderer's shading will make the sharp wrinkle at
the edge of a DEM grid look a bit darker than the rest. So you've proposed to
overlap one edge over the other – won't one of them still land on top, and one
will be visible, along with the darkness at its edge?
Enough theoretical talk. Have you tried this in 3D Studio yet? 🙂
