For clay and stone this is really useful. Am I missing something or is this not included in VrayforC4D

The roughness trhat you are talking is a propriety of the Oren-Nayar BRDF, that is basically a Lambert with a certain amount of specular, so you can simulate it with a diffuse and a specular with a very low highlite glossiness and Trace reflection deactivated.
