i’ve known pixar renderman since ca. 2005 when it first came out as a plug-in for (then) alias|wavefront maya. at that time it was the king for soft lighting, less technical than mental ray, with often unrealistic but beautiful results.
over the years i lost contact, and in recent months the → arnold renderer by the spanish programmers from solid angle served all my needs. it is just an amazing tool for lighting, texturing and rendering.
renderman is a direct competitor, and this is my first attempt to use it for a maya scene about → NURBS modeling. i’m quite impressed. the scene has a global and three local light sources. the NURBS fillets are depicted as highly reflective. nice, and not hard to set up.
