Chunk
I came in to Characters fairly late in the production of Toy Story 3. The work I did was mainly with models best suited to the model/sculpt pipeline I was helping to develop.
Chunk was the first character at Pixar that used displacement maps extracted from a high resolution sculpt. I did the sculpt and production model as well as the displacement extraction for shading.
Twitch
I was given Twitch as a rough concept and worked closely with Art to finish the design in 3d. I also executed the production model, displacement extraction and articulation.
