Terrain Self-Shadow (POM/Tessellation)
I am trying to get a basic 4 layer terrain shader using either POM or Tessellation functioning as I would expect. I am seeing the tech on both types working, but it looks like it's missing self shadowing or something. As when the POM material is applied to a normal cube, it looks great, but rubbish on the landscape, with crazy swimming at grazing angles. Upping the TempAA for the pom makes everything better, but kills performance.

Similarly for the tesselation, it's certainly tessellating, and deforming based on the height map, but it doesn't self shadow so you can barely tell. Also, "crack free displacement" is on, but there are still cracks (but not on the preview cube in the material editor view)

Is something wrong with landscapes, or do I need to do something differently?

You do not need crack-free displacement, when displacing only vertically. POM drift at such angles is expected.
