Are most materials going to be basically a BSDF input, as it is currently in Eevee? Or will components of diffuse, shadow, self shadow, ambient/world be available?
The NPR engine had different shading algorythms; (lambert, phong, etc) - will these still exist?
The curvature, edge detection, and similar nodes in NPR - will these still exist for materials?
Will AOV, math abilities and transparency exist at the material level, as they do in the NPR?
