Arnold Noice as Imager

[mckenzie2VER2]

Some confusion here over Noice.

Two questions:

1.

I've enabled Noice as the first imager in the ipr. I've also enabled:

Enable AOV's

Merge AOV's

Output Arnold Denoiser AOV's

as well as a location for the output.exr.

I've also added a display driver with the N,P and Z passes.

When I render via the IPR nothing happens.

What am I missing? I thought noice can applying NR after a render in the IPR?

2.

Lastly, if I load the output.exr into the Denoiser tab in Render Settings, it does denoise the image there but when loaded into the C4D picture viewer it's all washed out. I'm presuming this is because it's a 32bit file? How do I get it to display correctly there?

If you're using Noice as an imager, you don't have to do any of that.

All that other stuff is for the noice standalone.

[mckenzie2VER2]

Deleting it and re-adding fixed it. That being said, any changes I make to noice restarts the IPR, is that correct?

Also, can you answer the question re standalone noice. I.e. once NR is completed if I add that to the picture viewer the image is all washed out. Is that a C4D thing?

[Stephen.Blair]

NR?

I wouldn't use imagers when you're going to denoise with the noice standalone. The imagers will change the input AOVs to noice and you won't get the right denoising.

otherwise, the input and output images should be in the same color space

[mckenzie2VER2]

NR = noise reduction

We're talking at cross purposes here. I have two separate questions which I layed out in the OP.

1. Right now when I use Noice in the IPR, it restarts the IPR when I make changes to the noice imager. Is that normal?

2. If I use Noice as stand-alone, not in the IPR, when the image has been de-noised and I click to view the result in the C4D picture viewer, it is all washed out. I would like know why and how to resolve it (it's like is has the wrong color profile or something).

[Stephen.Blair]

1. I think it's normal

2. Run oiiotool -v --info on the noice input and the noice output. Should be the same color space.

can you add those switches in the denoiser in the c4d render settings?

oiiotool, Stephen was referring to, is a separate command line tool located in the arnold/bin folder. You can also attach the images (input and denoised) to this thread and I can take a look.
