Hey.

I was hoping that this issue would be fixed but it's still in the XB4 release. The Denoiser Beauty pass shows random passes instead of the actual denoised beauty pass. What is shown is hard to say, It depends on what other passes are selected.
For example. I just rendered out a scene with 4 passes. Combined, Material Index, Object Index and Denoised Beauty. The first three are as expected and the Denoised Beauty Pass shows a copy of the Material Index Pass.

It would be great if this can be fixed. Otherwise it's almost impossible to get the Denoised Beauty Pass to show up.

Cheers,

Hi AndreasResch,

It seems like that the denoise is disable. Could you please check the denoise setting in camera imager?

For preview render(CTRL+Z): "3D View - Octane Camera Imager - Spectral AI Denoiser - Enable Denoisiing".
For final render(F12): "Camera Object - Properties - Data - Octane Camera Imager(Render Mode) - Spectral AI Denoiser - Enable Denoisiing".
Please enable both camera imager and denoise.

Cheers,
DrawFun

AndreasResch,

I spend some time trying to figure out how to make the denoiser work. This is what you need to do.

Beside having Camera Imager "On" and Enable Denoising "On". A number of render passes have to be enable:

Turn "On" Render Passes,

Under Beauty Passes - must enable "Raw", "Emit" and "Environment".
Under Denoiser Passes - must enable "Beauty", "Direct", "Indirect", "Reflect" and "Reflection". If your scene has glass and Subsurface scattering enable "Refract" and "Remain" passes.

Last turn "On" the Z pass.

After rendering the "OctDenoiserBeauty" pass will contain the denoise image and "Combine" pass will have the non-denoise beauty pass.

Hello.

I've had the Denoiser ON. Weirdly enough, when I tried to replicate the problem it worked again. I will keep monitoring the issue and see what happens.

@eklein ... Thanks for the suggestion. When the problem occurs again, I will give it a try.

Cheers,
Andreas

DrawFun,

Preview denoiser does not work at all.

Denoising while rendering (Denoise on completion turn "Off") does not work in both preview and final rendering.

Eric

I can confirm that, but it didn't work in XB3 either. So I assumed that it is not implemented yet.

Andreas

Hey.

I managed to capture a error in a screencast. As you can see, even during the same session, at the beginning the denoiser pass works but when I split the windows and render again suddenly it doesn't work any more. On another occasion, which I did not record, it was the other way around. First it did not work an suddenly it did.

Here's the scene I used ... http://www.andreasresch.at/upload/Octane_Test_13.zip

I tried the suggestion from eklein but it it did not work with this scene.

Cheers,
Andreas

Andreas,

I can reproduce this error in the "OctDenoiserBeauty" pass with your test file.

I notice your are missing some of the render passes that the denoiser needs for it to work. If you do that it works fine.

As a mention before enable this render passes.

1. Beauty Passes: Enable "Raw", "Emit" and "Environment".

2. Denoiser Passes: Enable "Beauty", "Direct", "Indirect", "Reflect" and "Reflection". If your scene has glass and Subsurface scattering enable "Refract" and "Remain" passes.

3. Turn "On" the Z pass.

Eric

Hey.

I can't imagine that this is the intended procedure to get the Denoised Beauty pass, even if your method works. This is way to tedious and messy. Besides that, sometimes the Denoised Beauty pass works, even without checking all the other passes. This looks like an ordinary bug to me.

Let's see what OTOY has to say about this.

Cheers,
Andreas

I agree. It should work like in the standalone version. One Beauty pass and one beauty denoiser pass. My approach above is a workaround for now.
