Can you post a cube scene with that material ?

I sent you the file with the asset and materials / textures in a PM

Is it correct to totally disregard SHADING NORMAL pass & denoises anyway?

Eg.
Gold w Bump (Normal map), rendered to 5k samples (Halt Noise Treshold @ 6).

In latest sources and with OIDN v1.4, I'm pre-filtering only the Albedo pass but looking at the images I'm starting to think that it may be worth pre-filtering the normal pass too. I will do some test.

I think that looking at the results, the best course of action would be to give the user all the options, so there is a default behavior, but the user can go and decide what happens with each pass and how OIDN should treat them.

OIDN uses the Avg. Shading Normal pass (Avg. = Average).
In the Blender addon, it is enabled automatically behind the scenes when the denoiser is used.

Oh, so that's why details are gone. (Yes, avg. nrml pass was smooth)
Is there a simple way to switch it?

Switch what?

For OIDN to use "Shading normal" instead of "Avg." pass.

One important thing regarding OIDN 1.4.1:
