RfB provides truly seamless access to RenderMan’s speed, power, and stability for Blender users, who can maintain a simple, Blender-centric workflow, or take advantage of the plugins’ flexibility to create an optimal, customized pipeline.
RenderMan for Blender includes two different denoisers, the RenderMan AI Denoiser from Disney Research (see Denoiser) and Nvidia’s AI Denoising solution.
Nvidia’s AI denoising is not available for macOS.
Interactive Rendering
For more information about using the Nvidia denoiser in “it”, refer to the “AI Denoise” section in Image Tool.
The RenderMan AI Denoiser currently does not work in XPU mode.
For interactive renders (viewport renders, IPR to “it”), you can turn on the denoiser by going to the viewport preferences and selecting one of the denoisers under IPR Denoiser. Optix refers to the Nvidia denoiser.

You should see immediate results with. the Nvidia AI denoiser, like below:
This is the result with the RenderMan AI Denoiser after two passes:
For the RenderMan AI Denoiser there are some additional controls:
Cheap First Pass: if checked, the first denoise pass will use a cheaper (slightly faster but lower quality) heuristic. This can be useful if rendering something that is converging very quickly and you want to prioritize getting a denoised result faster.
Min Samples: the minimum number of average samples per bucket before interactive denoising runs for the first time.
Interval: the time interval between denoising runs (in seconds).
What’s New
RenderMan® 27 marks a historic leap forward with XPU production rendering, ushering a new era of GPU accelerated rendering at Pixar Animation Studios.
Upgrade
Production Ready
RenderMan XPU is ready for final frame rendering, ushering a new era of CPU & GPU rendering at Pixar.

Robust Compositing
With display and sample filter support, XPU now includes additional compositing capabilities necessary for visual effects, such as mattes, holdouts, and deep data.

New Creative Tools in XPU
Upgrade your stylization sandbox with a new set of non-photorealistic controls in XPU such as painterly styles, toon shading, and sketch-like rendering, as well as new in-shading pattern controls for easier artist workflows.

Interactive Denoiser
Now available interactively in XPU and all bridge products, the RenderMan Denoiser uses machine learning to deliver state-of-the-art results

Fast and Accurate
The Interactive denoiser is capable of removing noise on images with very low average sample counts and is predictive of the full offline denoiser.
Improved Performance
With full support for nested instancing, quicker hair rendering, better texture conversion, more flexible memory allocation, and multi-GPU support, RenderMan XPU is more robust than ever.
v27.1
Changes:
* The attribute “LPE Group” is now exposed on the object properties tab, under the Shading and Visibility panel.
Bug Fixes:
* A bug that caused AOVs to not render correctly when doing multiple renders has been addressed.
* A bug that may cause object instances via geometry nodes to transform correctly during IPR has been fixed.
* A bug that caused cloning/copying a PxrRamp node to crash blender has been addressed.
* A bug that caused NaNs to appear in the denoised result when rendering to the Blender display has been addressed.
