(You can read more about Bump to Roughness in this Pixar Research paper – See section 2.4). Currently Bump to Roughness can be implemented through custom shader patterns, and there is a OSL example implementation provided on Pixar’s tech memo page. It’s an area of recent research in a number of papers, which Pixar has implemented in our RIS bxdfs” explained Sisson. “The microfacet detail is created with Bump to Roughness. This comes from the new Microfacet details in the cloth. They look very similar but contain much more detail, which can be seen in the closeups. The materials on the suits of the Incredibles are much more complex than in the original film. This film has also pushed the boundaries of what can be done technically, and some of these innovations were previewed by Sisson in Germany last week. The next film from Pixar is the highly anticipated, Incredibles 2. A direct result of Coco, is that RenderMan, Light Discovery algorithm was greatly enhanced. As we documented, the Lightspeed team worked in concert with the RenderMan team to addressing this in a world with over 2334 practical light – including 729 point cloud lights, (equal to millions of individual lights). For example, in Coco there was 8.5 terabytes of cache data for crowds in the afterlife. In Coco, big sets, large crowds and vast amounts of lights all lead the developers to once again expand the limits of what RenderMan could handle. Pixar’s production issues always feed the RenderMan team’s R&D agenda, as we highlighted in our fxguide story on Coco. Those high end production lessons have been packaged up into new tools inside version 22. Like Bao, Coco is both a healthy celebration of a different culture, while being a technically complex project that allowed the RenderMan team to extend the renderer and solve new complex production problems. It was when she was working on Inside Out in 2015 that she decided to create her own side project. The company is now 100% committed to RenderMan as a Physically Based Path Tracer.ĭirector Shi joined Pixar in 2011 as a story intern. That maternal care inspired the story behind Pixar’s latest short film, which was rendered in RenderMan as a fully physically based path traced project. When Domee Shi was a little girl growing up in Toronto, her mother treated her like a precious dumpling, constantly making sure she was safe and didn’t wander away. In Pixar’s all-new short, a dumpling springs to life as a lively, giggly, dumpling boy, giving an aging Chinese mom another chance at motherhood.īao is the first Pixar short to be directed by a women, the first to be produced by Becky Neiman-Cobb, and the first short to feature a Chinese-American production designer, Rona Liu.īao is Domee Shi’s directorial debut. It is stunning, and another significant cultural contribution, to the increasingly balanced, Pixar creative diversity of projects. BaoĪs part of his talk, Sisson was able to screen for the FMX audiences the European premiere of Bao, Pixar’s new animated short which will appear before the new The Incredibles 2. RenderMan for Maya has been also completely rewritten and modernized, significantly enhancing the experience for artists with powerful new workflows. The rewritten RenderMan for Mayaįor RenderMan Version 22, the product has both technical innovations and speed improvements. As he is both a company guy, and a really good artist in his own right, his talks are always one of the best ways to appreciate the current roadmap for RenderMan. ( Dylan is also the guy responsible for the creation of the famous Pixar’s RenderMan Walking Teapot toy). Today he is still an active artist, and the creator of several award-winning independent animated shorts. Prior to Pixar, Dylan Sisson worked creating animation and VFX for games and commercials. Sisson joined the RenderMan Products Group at Pixar Animation Studios in 1999, where he has been engaged in the development and evangelization of RenderMan. Pixar’s Dylan Sissonĭylan Sisson is a technical artist with over 20 years of experience in animation and VFX. Given that this year is the 30th Anniversary of RenderMan, Sisson also looked back at some of the history of the product and gave a sneak peak into what is coming beyond the next release. At FMX last week, Pixar’s Dylan Sisson gave a preview of the upcoming release of RenderMan 22, featuring advanced light transport, greatly improved interactivity for artists, and integration with Pixar’s Universal Scene Description (USD in version 22.1).
