MtoA 4.2.4 - render sequence won't output Optix denoised shadow_matte AOV

I've tried all sorts of things but I can't get Optix to denoise my shadow_matte AOV when rendering a sequence in Maya 2022.

I've added the Optix imager, told it to denoise my shadow_matte AOV. I've given it an output suffix and I can see it in the Arnold render view. But when I render the sequence it only outputs the non-denoised shadow_matte.

And here's the noisy output:

There were no problems rendering a sequence of an Optix-denoised AOV in Maya 2019 but in 2022 it seems completely impossible.


I refuse to use Arnold Noice because in order to get decent results it takes even longer to calculate than to render at higher settings without denoising.

Works for me with Maya 2022.2 and the latest MtoA

But I'm rendering EXRs

I started out with 8-bit TIFs. But now as I try EXR I still get a noisy result. And no files with my output suffix.

Did you try Merged EXRs?

I'm logging a bug right now, because for non-merged output, the imagers are not linked to the Arnold drivers that write out the rendered AOV.

Besides using Merged EXR, I think another workaround would be to use an operator to set the input on the AOV drivers. I still have to test that...

Aaah, it seems to work with the merge AOVs option enabled! Thank you so much for the help, and with logging the bug.

I didn't know about operators, will have to educate myself :)

I made a test scene if somebody would be interested in trying. I must have missed some setting, because I still don't get a denoised render.

I should mention that I render via Render > Render sequence
