As a user I'd like to see the terrain details pop more (self shadow)

I had to disable the selfshadow code early on as it was badly messing up the coloration on land that was shallowly tilted towards or away from the light source.

3D rendering would likely take care of this, but there might be ways to get it back in operation without the odd effects.

Code is commented out near line 275 of OBBRenderer.cs
