Carbon reflective material associated with ward roughness

Roughness The Ward roughness model is based on an anisotropic gaussian distribution of slopes. Its roughness parameter corresponds to the standard deviation (RMS) of the slope. A value of zero corresponds to a perfectly smooth specular surface.
