denoiser maximum resolution?

[super gnu]

Im trying to render some 20k+ pixel wide images. they take ages, so im trying denoiser.


On my low res. tests, it seems the nvidia denoiser worked best, default denoiser seemed to ignore all the noise in this scene, and intel one seemed too heavy handed..

so i set a full res test going last night.

this morning its actually finished rendering surprisingly, but the denoiser doesnt seem to be doing anything.

the layer is greyed out, even if it the layer interface is available, with the opacity slider and the "update" button.... however nether of these seem to have any effect on the image...

the "vraydenoiser" layer is black.

any thoughts?

Looks like denoiser run out of vram.

You could try the standalone denoiser if you saved the render channels. It will let you set a strip size to process in chunks of a manageable memory size, though I have never actually tried that option.
