![]() ![]() To help avoid these issues, we are investigating several compelling ideas including Unity Labs' research on Microfacet-based Normal Mapping for Robust Monte Carlo Path Tracing," said Christophe. This might lead to dark non-lit areas on a piece of bumped geometry. Creating the Falco Rosso Pierre Bournigault shows us his creative process, from modeling to delivery, for creating a futuristic car in Maya, Mari, RenderMan, and Nuke. on the same side as the geometric normal), in order to keep a consistency with bi-directional transports. Download a project and follow along as Wei Wong breaks down his creative process for character creation in Maya, Zbrush, Mari, Substance, and RenderMan. The remaining big issue with Bump is that it is not reciprocal (at least as currently implemented) and we resort to alternative solutions (such as nudging the bumped normal to stay on the visible hemisphere, i.e. "There is more work to be done, in regards to Bump in general. Looking ahead is always in Pixar's DNA and Christophe Hery, Head of Pixar illumination group and research scientist, is already planning to expand RenderMan's Bump capabilities even further by implementing leading work in the field. This overall improvement in sampling variance has led Pixar to new heights of image quality when defining micro detail, in which quality doesn't have to compromise render times. "Future feature films at Pixar are using Bump Roughness with great success, from skin shading to shading most arbitrary assets, the improvements to detail preservation are the new status quo for surface quality," said George Nguyen.
