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.
