Title: Corona render 3 for Max denoise
Post by: Pavlov on 2019-02-27, 16:41:39
Hi guys,

I have recently installed corona 3 for Max and I found it a bit heavier than the previous version during the interactive render, I have noticed after the first few passes there is an automatic denoise that blur everything and it's quite annoing, is ther eany way to disable it and see just the pixels pass by pass as the previous versions?

Thanks in advance

This is the NVIDIA Optix denoiser and yes, you can disable it.
Under the performance tab -> bottom right "Fast preview denoise during render"
as described in the helpdesk (https://coronarenderer.freshdesk.com/support/solutions/articles/12000053263-how-to-toggle-the-nvidia-gpu-ai-denoiser-for-regular-and-interactive-rendering-), where you can find answers for all kind's of questions.
I personally have it disabled too ;]

I find it to be a little too powerful as well, or at least it's applied too early. You easily lose a lot of surface detail. If there was a way to have it denoise later, it might be better.

In V4 (currently daily builds) we have:
- Denoising checkbox and spinner which can be used to toggle denoising on/off, also in IR
- Intel denoiser which is applied only when rendering is finished

thank you guys, the answer was exactlky under my nose. I turned off and now it's much faster.

Thanks again

In IR? Are you talking about daily build 2019-03-01 maybe?


Good Luck

Sorry, you are right, it does not work in IR...

Anything new in V4 in this regard?

Thanks.

In which regard exactly? :)
The NVIDIA denoiser is still available for IR.
You can use it later (after rendering) by either unchecking the "denoiser" checkbox (not available in IR), or saving your image in CXR format, opening it in CIE and then applying denoising.

Hi Maru. Sorry.
Regarding:
In IR, the availability of some control of the intensity or how fast the denoising happens.

Someone else said it better:

"I find it to be a little too powerful as well, or at least it's applied too early. You easily lose a lot of surface detail. If there was a way to have it denoise later, it might be better."

I think best would be to make the denoising amount spinner work in IR, that way we'd have full control over its strength and could turn it off if desired. Also it would be more consistent in terms of UX since it already works that way in final render mode.
