[Olivera2708]

Remove Monte Carlo noise by applying denoising algorithms.

Or use AI
Why is it cool?

Makes your path tracer much faster by removing noise instead of increasing samples.
Used in Blender Cycles, NVIDIA OptiX, and Pixar’s RenderMan.
You can use Intel Open Image Denoise (OIDN) or train your own model.
