Material testing, curvature filtering and specular response - also anisotropic reflection. Stanford dragon from the scanning repository, Bryce sun, one diffuse radial light, 3x TA gel lights, one TA firewall, HDRI for reflection, boost light, TA render, soft shadows, DOF and blurred reflection. 64 rpp render time twelve minutes.
Thank you. We (Horo and I) have begun work on a sequel to this [link] this is a material test for the next one. I wanted to include more curvature filtering, because it is a largely overlooked feature.
