Extremely Grainy renders in Maya 2022 - Arnold renderer?

[kenne150]

Hi. I just upgraded to Maya 2022 from Maya 2018 a few days ago. I'm having a lot of problems finding render settings for a decent render. I used these similar settings in 2018 and got clean, crisp, renders. Now I'm having quite a bit of noise and grain. I've attached screenshots of my settings and of my render. You can see the excessive noise on the transmission and specular, and over all it's just a crappy render. It's  set to 1920 x 1080. There's only 1 light and it has 4 samples. I have a some emission on the lampshade. I'd appreciate suggestions. This quality of render is not acceptable for what I'm doing... thanks.

The images were too many images to uploaded, here's a link to them on Google Drive:

Hi!

I guess you used CPU rendering with Maya 2018 and now use GPU rendering in Maya 2022.

GPU rendering needs much higher sampling settings, increase the value for Camera AA, you can also use Adaptive Sampling.

Thanks. I will try this. Hope it helps. I found something called Optix Denoiser, which helped with the grain, but really made the transmission look kind pasty. I have some glass textures, and it really seemed to make the glass not as transparent.

I also can't get the noise out of my transmission heavy materials, without cranking setting ridiculously high.

Edit: I was able to get it pretty good by really fine tuning the adaptive sampling. I put 20 samples in adaptive and set the threshold at .05, which seemed to even out the samples a bit better over the entire image. Then I used the regular sampling to get it to where I wanted it before denoising. Still more noisy in the transmission but useable.

I finally gave up and went back to the CPU. My GPU samples were so high, it was taking 10x longer to render... which defeated the purpose, for me, of using the GPU. 😕
