Imagers not showing in final Rendering AOVs

[gfx4Y4RTN]

Hey Maya and Arnold Experts!

I have a problem when I try to render Single Frames with the Arnold Render View, that have an Imager applied to them.

I check the box for "Save Final Images" so when the rendering is finished maya should save all my passes, I render with the GPU in png and 16-bit format, because open EXR and 32-bit is just not suitable for our workflow. I want to denoise single AOV passes that get especially noisy, for example "Transmission". But when I select the AOV in the Imager the final saved image is never denoised. I have tried a lot of different approaches, unchecking "use feature AOVs", rendering an Image Sequence etc. ... Nothing seems to help, the Images will always be noisy, except for the beauty pass, which always works (the only exception).

Can anybody tell me what I am missing or are the Imagers just not suitable for non exr AOVs, haven't found an explanation in the documentation als well.

Thx in advance!

This is unfortunately a known issue. For reference, here is the ticket:

• MTOA-935 Exported drivers are missing imagers when you have non-merged output

To apply any imager to a layer selection (individual AOVs besides the beauty), you'd have to render to EXR with Merge AOVs enabled).

Thx for the quick answer!

I hope it will be fixed soon. Not everybody always renders in exr format.
