/cc @meetar for assistance with "muting" the normals in areas of low relief (valley floor).

Re: less noise in the low relief areas: I've experimented with a number of code adjustments, but the simplest way I've found to do this so far is to manipulate the spheremap, specifically by enlarging the center area's color. Eg:

colorwheel

Produces:

smooth-valleys

This also means you lose nuance in other areas of low relief, not just valleys, but that's going to be the case with any method, short of some other kind of valley-detection analysis.

Thanks for the tip! We’ll try opening up the center, but adding a little generic texture across it to keep the look consistent.
