Hi,
I'm having some trouble using Noice in c4d; i've tried using a suggested workflow by Stephen Blair, in an old post, but it seems i can't get it to work.
Basically what i do is:
The problem i'm having, is that it doesn't save the denoised file in the specified position, or in any other one. The console reads as follows:
-----------------
Denoising image: test3.exr (1/1)
"/Applications/MAXON/Cinema 4D R19/arnold/bin/noice" -f 1 -pr 1 -sr 18 -v 1.000000 -ef 0 -i "/Users/Marco/Desktop/test3.exr" -o "/Users/Marco/Desktop/test3_denoised.exr"
noice 5.2.0.0 [4fb9451c] - the Arnold denoiser
Loading images...
Loading file "/Users/Marco/Desktop/test3.exr".
Working with 1 frame.
Start denoising (patch radius 1, search radius 18, variance 1)
Finished denoising
The number of output paths does not match the number of inputs.
Denoising image done in 00:00:00,211
==================
Denoising 1 image completed in 00:00:00,214
-----------------
Right now i'm using the 2.4.0.1 version of Arnold.
I'm definitely doing something wrong, but i don't know what. Can someone help me out?
Cheers

You're using an older version of Arnold, so first thing I would do is upgrade.
Then I would check that test3.exr is not a flat exr, and that it really does have the extra AOVs that noice requires.
The noice log should list feature AOVs and mention variance

Hi Stephen,
I think i managed to solve my problem, i was missing the 3 AOV specified in your log and i was rendering with the "driver_c4d_display" enabled, instead of the Arnold denoiser.
By the way, why is noice requiring the diffuse_albedo, N and Z AOV to denoise the image?
I couldn't find any info in the support portal.
Thanks
