noice.exe and single layer exrs

Hi,

Is noice able to work with single layer exrs? I know that previous version (5.1.0.1) did not support this, however, reading through release notes on 5.1.1.0 i was under impression this has been implemented.

https://support.solidangle.com/display/A5ARP/5.1.1.0

noice support for AOVs from multiple files: noice now supports multiple input files to be denoised. These can be specified by using the -i (--input) argument as many times as needed. Multiple output files are also supported to preserve the original AOV layout.

Example given beneath that paragraph is not exactly what im looking for, but it does suggest we can now input AOVs as separate files.

I tried something like this on a windows machine:

noice.exe -i beauty.exr -i diffuse_albedo.exr -i N_noice.exr -i Z_noice.exr -i variance.exr -pr 8 -sr 16 -v 1 -o beauty_denoised.exr

but noice crashes.

This is the only output i get:

noice 5.1.1.0 [e338d869] - the Arnold denoiser
Loading images...
Using 8 threads.
Loading file "beauty.exr".
Loading file "diffuse_albedo.exr".

Loading file "Z_noice.exr".
Loading file "variance.exr".
Using feature AOV 'diffuse_albedo'
Using feature AOV 'N'
Using feature AOV 'Z'
Working with 1 frame.

After that it crashes immediately. No errors or anything.

I don't know if separate AOVs for features is supported. All the tests I've seen have the features in one exr.


And you definitely won't be getting variances for those AOVs. That's not supported yet by MtoA.

From the 5.1.1 release notes:

noice custom features: For advanced users, the new flag (-fe or --features) specifies which AOVs will be used as features to guide denoising. For instance -fe volume_albedo will use volume_albedo for denoising instead of the default diffuse_albedo, which will improve the quality of denoised volumes.

it worked with using an second driver with variance filter

Thanks for that input !

What's the commandline option -fe "Use this AOV as a denoising feature" mean?
