Overview ¶
NVIDIA’s OptiX AI-Accelerated Denoiser uses deep learning to remove noise and “fireflies” from a rendered image. It is useful for getting a higher-quality preview of what a converged image will look like so you can make lighting decisions faster.
-
The NVIDIA OptiX denoiser requires an NVIDIA GPU with Kepler architecture or better.
-
The denoiser is not available on macOS.
How to ¶

In the parameter editor for the Mantra render node, click the Images tab, then click the Output sub-tab. Click the drop-down menu button next to the Pixel filter field and choose “NVIDIA OptiX Denoiser” (sets the field to In the Pixel filter field you can optionally specify an image plane to use as the albedo input to the denoiser with the denoise optix -a mydiffuse |
