I personally did the lighting and rendering for the Reveal Image. The original silhouetted image of the truck was done by fantastic CG artist Dave Hudson.
For the other shots I assisted by rendering out shadow, matte, and occlusion passes. For all of those shots, Cy Kelcavic and Conor Fitzgerald executed the Lighting, adding the Material Shaders and Passes. Rip Evans, Aaron Brothers, Matt Sommerfield and Jeff Bergmann did retouching on all shots.
It was great to be a part of this job. Its too bad I didn't get a shot of the countdown screen that was a constant reminder of how long we had left to finish this.
