Arnold exr3.jpgHello,


thank you!


So i wrote the diffuse in for the test. Then another error occurred and the disffuse is not included. It probably doesn't have a variance layer.

Error:

Will just copy AOV "diffuse", variance not found
Output file will be "E:\Test\Arnold exr\Test Neu2\Versuch\Test_denoised.exr"
Start denoising (patch radius 3, search radius 9, variance 0.5)
Denoising RGBA
Denoising diffuse
Could not find AOV with source diffuse and filter variance_filter
Could not find variance for AOV "diffuse", skipping denoise.

According to the log: "Will just copy AOV "diffuse", variance not found" means that the diffuse AOV just copied over to the output without denoising. I made a quick test and it's there.

The Arnold Denoiser writes out the denoised AOVs, which is only the beauty (RGBA) by default. To output additional AOVs, list them in the Light group AOVs field, for instance in your scene:

diffuse specular background object_mask1

If they can not be denoised (e.g. no variance layer exist for an AOV), then they are just copied to the output.

Seems like something's broken with that Read button, I'll take a look.

I don't see any AOVs listed in Light Group AOVs, except for that "background" aov.

Only the beauty is denoised, and only the denoised AOVs are output by the denoiser.

You have to add other AOVs to the "Light Group AOVs" list. They don't have to light group AOVs, they can be any AOV...like "diffuse"
