Using ZBrush in Dinosaur Revolution
Zbrush was used extensively throughout this project and as Lead Texture Artist I thought I would breakdown some of the contributions I made using ZBrush on Dinosaur Revolution. As lead texture artist I was brought in to help create a pipeline that would take the dinosaurs modeled in ZBrush by David Krentz and his modeling team through texturing and shading, and send them off for animation and rendering, insuring quality and functionality. We looked at other texturing programs, but quickly settled on ZBrush’s Polypainting function to texture our dinosaurs.
This Showreel hightlights many of the creatures I textured for Dinosaur revolution. (Additional creature texturing by Bryant Hardwick, Aaron Hammon, and Angie Rodrigues)

For Dinosaur Revolution I was tasked with leading a team of texture painters in creating close to 200 photo-real dinosaurs in a short time. My tasks included working with the Creative Director and the VFX Supervisor to ensure the quality of the the characters up to the final render process.
Polypaint gave us the ability to use the sculpts themselves to aid in the creation of the textures with functions such as cavity masking, spray brushes, and alphas. Having Zbrush available for the texturing process made creating all the secondary texture maps much easier. We were able to use Zbrush to create highly accurate cavity maps based off the displacements which could be used in the creation of dirt maps, reflection maps, and even in the final diffuse. With Polypaint creating specialty maps, such as gloss maps were a breeze .
Although I was not one of the modelers that created the dinosaurs for the show, I did get the opportunity to detail and texture close-up heads using ZBrush’s HD Geometry feature. The stories in Dinosaur Revolution were extremely character based, so for some important shots the director David Krentz wanted to have ultra close shots of the main character’s faces. The details added on the heads of Torvosaurus and Allosaurus were all done by hand, each scale painstakingly added to match the original model.
Also David Krentz, the director and modeler of many of the dinosaurs is hosting a preview workshop FOR FREE at Creature Workshops on Nov 10 at 10 AM Pacific Time ( california ) that will go over the same techniques used for these dinos. Register at this website. http://www.creatureworkshops.com/
