![]() ![]() Coming out of the course the student will be able to put into practice, in a production environment, the procedural shading techniques we cover and understand their use more thoroughly, as well as design a shading/lighting pipeline around the physically-based shading and lighting paradigm. Artists and Technical Directors will find this course useful for expanding their shading knowledge in Renderman, as well as learning some of the newer advanced ray tracing, physically-based shading, and image-based lighting techniques being used in production today. With this new capability, we’ve seen up to 2x faster full renders, and 15% average speedups on a wide range of Pixar scenes using Intel Xeon Scalable processors with Intel Advanced Vector Extensions.Taught by Christos Obretenov, this course covers the use of the software in production. “We are excited to launch RenderMan 22.5 with a new feature: SIMD hardware acceleration of OSL. Pixar has seen up to 2x faster full renders and faster time to first pixel on production assets, with 15% average speedups measured on a variety of real scenes using the power of Intel® Xeon® Scalable processors with Intel® Advanced Vector Extensions (Intel® AVX-512 and AVX2).These vectorized OSL capabilities are available in RenderMan today, and the source code is available upon request while the collaborators work to contribute it to the open source OSL project.It dynamically schedules concurrent operations on 8 or 16 data points in a single CPU instruction depending on available CPU capabilities. This new OSL implementation shipping in RenderMan 22.5 includes parallel execution of the entire shading network on Intel’s SIMD hardware.Senior developers at Intel, Pixar, and Sony Pictures Imageworks collaborated on this important project.RenderMan and USD are the backbone of Pixar’s production pipeline and RenderMan Development is working closely with Pixar’s USD team to make USD a first-class citizen within RenderMan. Universal Scene Description (USD) is Pixar’s open source file format & API for describing CG scenes & data in a ‘composed’ manner to facilitate concurrent workflows across multiple applications & artists. The integration is tight, it makes it easier than ever for our Houdini artists to work in Renderman! We’re all very excited to see the Houdini/RenderMan workflow get better and better,” said Chris Rydalch, Production Technology Technical Director, Blue Sky Studios *Houdini Indie support to be available with an upcoming future 17.5.229 release.Plugin is available for download from Pixar on supported Mac, Linux, and Windows OS.Preset Browser – Collaborate with Maya and Katana by importing and exporting shaders, light rigs, and HDRI maps.Texture Manager – Automatic texture conversion to Pixar’s texture format.Support for rendering to Houdini’s native mplay framebuffer and renderview.Support for Material Builder shader networks using RenderMan’s shading nodes.Interactive manipulation of light filters.Interactive editing of lights and cameras.Interactive placement and deformation of geometry.Full support for geometry: curves, points, volumes, meshes, and packed primitives.The plugin brings interactive modeling, shading, and lighting. Pixar’s brand new RenderMan for Houdini plugin has been updated to support the latest interactive workflows in RenderMan 22.
