Since Corona it's a CPU engine I think it will be great to integrate this new tool: https://www.techpowerup.com/251984/intel-launches-free-open-image-denoise-library-for-ray-tracing
It's similar to the Nvidia AI denoiser but runs on CPU(for free), please developers give a look because I think many of us do not want to waste money on pricey Nvidia GPU using proprietary tech just for denoising.
Seems that Intel AVX will speedup things but as far as I can tell it should run on AMD CPU as well.

Thanks for notifying us about it. We will definitely look into it. We will post some notification if/how/when we could use it.

Thanks maru! I have always used AMD GPUs since none of my software uses CUDA, it’s important to give people like me an alternative to the pricier Nvidia AI denoiser.

The sponza example in their gallery looks too good to be true, there's a lot of detail in the stone texture that just isn't there in the un-denoised version. Are they stretching the truth a little or is that the AI magic? https://openimagedenoise.github.io/gallery.html (sponza, 4th image from the top).

No. It is a cherry picked example though.
Most information comes from the passes that are not involved with shading.
See this paper's youtube video that basically started it all: At 3:42 they show how the different passes are composited. The Albedo pass caries all the texture's color information that got barely resolved in that 4th picture.
However, the lighting on the walls is very low frequency in content, so all of it smears together nicely into correct uniform lighting. Ones high frequency content comes into play (detailed bump, Wood textures, carpets) all these filters start to fault with too little render time.
Impressive without a doubt though.

Interesting, thanks!

I think this solution is not any better than what we already have, ther’s plenty of good denoiser out there for both interactive preview and final frame, the point is that this will work on CPU so we don’t need to use pricey GPU in order to get interactive results.

Chaosgroup is already testing the Intel denoiser with Vray. Quality seems good, I've asked Vlado about the performance.

now we have prototype in corona too ;)

Well, that was fast! :)

Please make that all 3 denoisers would work at the same time with combined cleaning power! :]
-

Great news :)
Please don't forget to add this feature in Cinema4d too!

"without it, the scene would have taken almost a yer to render" lol

Already in V4 dailies.

Hey Maru & Corona team,
the new CPU AI denoiser seems to work quite nicely in the Core 4 beta. And it creates such a realistic look due to the intelligent denoising which seem to react on the camera focus.
Also the displacement is great now, when stacked materials are used on poly selections!
In core 3, both features were (are) horrible - thats why some of us users asked for older betas.
But now, with the new Core 4 beta... wow ! Great times are back again.
Thanks so much to all of the Corona team, the big efforts you invest, and especially your openness for suggestions and critics from us, your customers.
Now, with the Core 4 beta, Corona really rocks!
Will be a great release!
