In the Object Type rollout, click Arnold Light. GPU denoised and how it distorts the geometryĬPU AA:3 and diff and spec ray depth set to 1.You can open the Arnold lights from the Command Panel’s Create panel ( )> (Lights) by selecting Arnold from the list, as shown here. Even a single 1 point increase in ray depth causes this much noise? Is that normal (see my request above to share my file)? I assume this makes sense since higher the ray depth the more bounces occur (which then generates more noise).īut take a look at the GPU set to AA:3 and the diffuse and specular depth both at 1 and then compare that to when I set the renderer to CPU. I am now actually concerned that my GPU is damaged or not working properly because my GPU denoised render images are so bad that when the denoiser kicks in it actually distorts the image! I set the ray depth 3 for diffuse and specular as you do on your example pictures but those are even noiser. That helped me to pinpoint issues as you recommended but I am ultimately aiming for a production quality low noise render of max 120 seconds per frame. I also want to emphasize that I care about the production render a lot more than the active shade.
If you have other ways of receiving files please let me know. I almost want to send you my file so you can see if something causes my high level of noise. That checkbox in the AOV manager window actually activates the OptiX denoiser? I thought that was a different denoiser there.
Very helpful but I need to bug you a little more I apologize. But then I will lose material reflections right? Ok, I think I am getting closer but still I am not sure how to get this resolve. Is this supposed to improve when i increase the specular and diffuse ray depth? By the way not sure if you saw but you cannot change the ray samples for specular and diffuse when in the GPU mode! When I turn the specular and diffuse to 0 I get a very fast render even with CPU. I keep AA at level 3 and you are right does not change the quality much increasing it. here they are with current settings (camera AA:2, diffuse:1, specular:1):īY far specular and indirect are the noisies are the noisiest passes. I also performed what you recommended and added each AOV to the activeshade and fired up the active shade to see the different passes. EXR denoised images were created even with the production renderer, so I guess I could just use those denoised images as my final render result? Are these denoised AOVs flicker less than the OptiX denoised ones or they are pretty much the same in quality. i would like to take full advantage of it.
