What are the ideal settings for noise free speedy renders on arnold gpu? (For animations preferably), Animation rendering on a single system gpu finally seems possible with this gpu version. All suggestions for settings are welcome. Thanks in advance.
There is no generic simple answer.
If we go for speed exclusively, start out by grinding all passes with OptiX.
The passes that fails, due to lack of deffinition or something else you render out and denoise with noise.exe
I've done production animation VFX with OptiX, so it is possible. Its not just a gimmick feature for fast previews, it does work, especially on high velocity stuff /mblur etc.
But for core settings, use the adaptive sampler and utilize the inv_density_AOV to probe where rays should work the hardest, cut things off - stuff the denoisers can get rid of, its a balance thing, case by case.
