Trouble Denoising AOVs with noice

[ethan.crossno]

I'm working on getting a noice denoising workflow setup at our studio and I'm running into some problems. I've got an EXR that I have rendered with 2 light AOVs lgt_blue_bty and lgt_red_bty. I have a variance AOV for each of these lights as well which is just the same LPE with the variance filter. I've been reading through the docs and I cant see what I'm doing wrong here.  I'm including the EXR file that I have for testing. Maybe someone can tell me what's wrong with the EXR file I have.

This is the noice command I was running: 

"C:/Program Files/Autodesk/Arnold/KtoA_4-2-2-0_katana_6/Libs/../bin/noice" -i "E:\Tempest\denoise\arnold_denoise_test.exr" -o "E:\Tempest\denoise\arnold_denoise_test_denoised.exr" -l lgt_blue_bty -l lgt_red_bty -t 44 -pr 3 -sr 9 --variance 0.5 -fe brz_albedo -fe N -fe Z

Is this what you got?

Yes that is the error I was getting. Seems like its not finding the channels or something like that.

Did you ever figure this out? I can't make it work. I have all my aovs in different exrs and I can't seem to be able to denoise lightgroups (I'm using the -l flag).
