This is my unfinished submission to the Renderman "Rolling Teapot" Challenge over at the PIXAR Renderman Forums.
Model developed by Brice Laville Saint-Martin, and designed by Tom Robinson
We weren't allowed to alter the silhouette or typology, unless a vector displacement was used.
I utilized the now (somewhat) unsupported Blender to Renderman plugin.
I sculpted all the displacements in Blender and then baked out the vector displacement maps to be used by Renderman.
I textured primarily in Substance Painter with mild editing in Blender, as well.
