I'd love to see more procedural textures in ProRender, such as a procedural scratches texture. That'd be great for UV-less realistic surfaces.
Keyshot has quite a good procedural scratches texture, with tapering at the outer ends and optional curvature.
Hmm, we don't do any procedural node networks. I suppose that is something we could do in the material library. What you really want is either a texture of scratches and then project with procedural UV's or to have something like a procedural texture network (like a substance network) to do this.
