Blender 4 – Renderman v26.2 Addon Free Download
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).
