Hi, I just looked at pictures, this is thrilling ! Have you tried lowering the
brilliance finish parameter slightly below 1.0 so that it more closely matches
the high (oren nayar type) sigma of lunar rocky surface? ambient should be 0 and
it also looks to me like diffuse reflectivity could be very slightly lowered to
keep corresponding contrast once brilliance is tweaked (specular seems spot-on
though !)(if using latest POV, maybe even just using albedo keyword would be
