Renderman Challenge 2: Rolling Teapot


For this second Renderman Challenge “The Rolling Teapot”, we got to work with a model developed by Brice Laville Saint-Martin, and designed by Tom Robinson, which providing us with a production-quality scene to showcase our shading, lighting, rendering and compositing skills.
Using RenderMan’s holdout workflow in order to create a realistic and compelling composite of the Rolling Teapot. Again, a great opportunity to test our custom renderman shader we developed together with Christos Obretenov from Lollipop.

The theme of the final render was entirely up to us, so we created a fun background story. There is an inventor who has designed the teapot artist. In the image we see the artists desk. On top the desk we see the prototype drawing. The artist (evil girl) is angry at a drawing of a boy goofing around with tea. Spilling the tea on her drawing, how dare he!

On the desk we have a technical drawing of the prototype, prototype stuff like a 3D printer and a hand drawing made by the prototype.

We used Nuke to combine our different AOV’s and the background photo to create the final image. We used AOV’s like basecolor, diffuse and occlusion. The hatching and paint strokes are created through textures in the occlusion and the diffuse.

A big thanks to Helen van Vliet for letting us use her studio and drawings as our background!

Renderman Challenge: ‘Kitchen Sink’


The first Renderman Challenge ‘Kitchen Sink’ gave us the perfect setting to test our custom renderman shader we developed together with Christos Obretenov from Lollipop. We are combining occlusion with hand drawn textures and diffuse rendering. For this test, we didn’t want to just render an image, so we created a proper background story.

Nonna and Tom baking cookies

Beach cabin on the large beach at the lido, Venice. An old lady and a dog are pottering about in their tiny summer house. Nonna is making cookie dough and Tom, the dog, is salivating in anticipation that he can have a bite of the dough. As Nonna is moving back and forth between the mixer and fetching ingredients from the cupboards, Tom is circling around her and when Nonna trips over him, she scolds friendly.
When the dough is finally ready and she wants to get the baling tray from the oven, Tom cannot control himself anymore. He puts his paws on the kitchen top where the bowl stands, pushes it over and with two large gulps eats the dough. Nonna is very disappointed.

To create this image we used a single custom shader that renders different AOV’s like basecolor, diffuse, outlines, occlusion. The hatching and paint strokes are created through textures in the occlusion and the diffuse.

Claymodel Nonna

What better way to get a good sense of size and shape by making a clay model of Nonna and the dog. We will make two models of Nonna. Here you see the overall model. Perfect to test Nonna’s shape and size but with less detail in e.g. het face. We are busy making a second clay model of only her head, so we can really create every wrinkle and characteristic of her face.

Study of Nonna

Nonna is an older Italian grandmother, but what should she look like? How does her size and shape relate to that of the dog? Helen van Vliet made some studies of Nonna’s appearance.
