Pixar’s Finding Dory(2016) and the short film Piper (2016) utilises RenderMan 21, the rendering power of it is from the RIS technology. It is used in both the animation and film industries, as the software is reengineered it is reflected in the quality of the films that use it.
Read a full list of new features in RenderMan 21.RenderMan is as rendering software that was created by Pixar, they released the first commercial version in 1989, it has since become “the industry standard software for rendering computer graphics in film.” (Pixar, 2017 p.8).
Versions 15 and above of Houdini contain their own integrated interface to RenderMan. Integration plugins are available for Maya 2015 and above, Katana 2.0 and above, and Blender 2.76 and above. New licences cost $495 the upgrade is free to users on maintenance. RenderMan 21.5 is is available for 64-bit Windows 7+, Mac OS X 10.9+ and Linux glibc 2.12 or higher and gcc 4.4.5 and higher. There are also a number of smaller features and speed boosts: you can find a full list via the link below. RenderMan’s Denoise tool for removing noise from renders as a post-process also gets an update, making it possible to use on exported EXRs “after a compositing process” if channel names and data are preserved.
The technology features in a panel on new advances in hair rendering at this week’s Siggraph 2017 show. The release also updates the Marschner Hair Shader introduced in RenderMan 20, adding new art-driven, as opposed to purely physically realistic, controls for remapping colour.
Updates to the Marschner Hair Shader and Denoise tool Pixar describes RenderMan as the “first commercial renderer in the industry to ship with a physically based model for subsurface scattering: based on deep path tracing and albedo controls”.Īccording to Pixar, the new mode simplifies the process of recreating materials like human skin, “providing an accurate result with a single set of controls instead of combining other techniques with Single Scatter”. Perhaps the biggest single change in RenderMan 21.5 is the new path traced subsurface scattering mode in PxrSurface, the software’s versatile multi-purpose shader. The first physically based implementation of subsurface scattering in a commercial VFX renderer Pixar has released RenderMan 21.5, the latest update to its production renderer, adding a new physically accurate path traced mode for subsurface scattering, and improved hair shading and render denoising.
