why thank you, its a shader graph job that samples orthogonal matcaps using post-animation world space normals. Rendered two different sets of spheres in blender for the matcaps, one shiny/reflective, the other reflective but with a bit of roughness, and blended between the two using a third uv-mapped texture generated using 1d voronoi noise. All because URP web build doesn't have ss reflections, at least afaik.
