Hi! I'm currently having issues with noise reduction in Arnold. I'm unable render when I turn on the Apply Beauty mode in the OptiX Denoiser. I'm looking for ways to lessen the noise in my renders and some of the ways I've found is by increasing the Camera Quality (AA) and manipulating the Variance in the Denoiser section.
Are there any other ways to lessen the noise?
Thanks!
Optix is intended for interactive production render previews, not final renderings.
For final production renders, use the Arnold Denoiser AOV workflow, aka "Noice".
To reduce noise in directly illuminated areas, increase the number of Samples in the light(s). I find that a value of 3 to 5 removes a great deal of noise in the directly illuminated areas.
For noise in indirectly illuminated areas, you can increase the Diffuse Samples. This will reduce noise in the bounce light areas.
Adaptive Sampling can help in many cases. The default values are insane, causing render times to be incredibly long. I recommend Camera AA samples = 3 and Adaptive Samples = 5 as a starting point.
Are you having issues with both Optix and the Arnold Denoiser?
What does the log file say?
I suggest going through these Removing Noise tutorials.
If you upload some images we can maybe see where the noise is coming from and advise which samples to change.
