Anyway, I ended up making my own nav-mesh generator, to satisfy my need for nice and orderly shapes.

It uses the vertices and surface normals in a given mesh, to decide what surfaces should be part of the nav-mesh.

And far as I can tell, it's working beautifully.

Edited screenshot from the Godot Editor, showing a chunk of 3D terrain, with a series of planes running along the uppermost surfaces. They change color for green to red, based on the steepness of the surface. Above this is a rough chart with dot-product reference numbers, for determining the surface angle mathematically.
