Denoising workflow

[mahmoudkeshta]

Hi,

I am a bit confused about the correct workflow of denosing. In some previous builds I was adding additional pass called " Beauty " with denosing amount and then do it in post or I use it directly the render setting ( which is not preferred for me) . Now when I add "Cshading_Beauty" pass it has no effect at all even the denoising amount is 1.0 and denoiser is enabled in scene tab it only brings the original render without denoising. can anyone tell me the correct workflow If I want use denosing as a separate pass ?

[Ondra]

did you adjust the denoising amount in the beauty element?

[mahmoudkeshta]

Yes I set it to 1.0 . Here is my denoising setting :

Scene tab > Denoising > Denoise mode : full denoising > Denoise amount : 1.0 , Denoise radius : 1.0

Render elements tab > CShading_Beauty > Denoise amount : 1.0

What I get is denoised image in original pass (Beauty) and when I switch to CShading_Beauty pass I get the render without denoising I don't know if this is normal or not. The workflow is reversed compared to previous builds.

Hi there,

True this vale has been changed towards 0.
Most people make use of denoising which shows up in the beauty pass. And in most cases denoising thus a great job.
In a few cases you could loose some details. In the latter (in post production) you could make use of the C-shading Beauty pass element without denoising and paint back in the details that has been lost.
That's why 0 should be the default value for the C-shading beauty pass.

I do not get it why you would like to have denoising as a separate pass?
But in post you can always make your C-shading beauty pass (with denoising value 0) as your base layer and the beauty pass on top as a denoising layer.

The spinner seems to be just broken, at least in DB 2016-04-29.

@belly: Yes, 0 in the beauty pass should be the default. But denoising in a seperate pass offers more options. Not only that you can have one denoised and one non-denoised result but also one denoised with 0,5 and the other with 0,7 to without going through post(!). It should be up to the user´s liking and ... it should just work :)

Good Luck

Ok, that's another point of view.
But I'll guess, at least for high res images, you need a lot of Ram for different denoise passes.

[Frood]

To be honest, I don´t know right now if denoising in this case is done consecutively or simultaneously (but I presume the first, so this would not be problematic) but hey, I can´t test it right now without reverting to a previous build ;)

Let´s test the next DB,
Good Luck!

Hi,
Burning denoising in original render directly is not good idea in my opinion because you may forget to save or even add the CShading_beauty pass then close corona and 3ds max and you will lose the original render data.

Totally agree

FYI:

It´s fixed in DB 2016-05-01. But notice: the spinner in beauty RE is from 0-100 (%) now. And default is... zero.

Good Luck

Yes it works well now maybe it was working before and I used value as 1.0 not 100 :) . It will be better to insert % sign to inform user that it is a percent value.

Another issue. I must enable denoising in performance tab to be able to use CShading_beauty pass is this a necessity ?

It will be better to insert % sign to inform user that it is a percent value.

Afaik today it was changed to be 0-1 everywhere in the UI so in the next version there will be no more confusion.

Good Luck!
