By the way, there was a moment in this presentation on SIGGRAPH when they said that pixar used AI denoiser in *fiding dorry*

https://www.ustream.tv/NVIDIA - He is speaking about it at 7:00-7:30

Funny, but i've heard "they created AI based denoising" ;]

Obviously first they had to create it =D

Beware that NVIDIA itself says that this denoiser is not good for animations. Sorry, we kinda forgot to add that info to the denoising mode tooltip (will be fixed in next build).

Well yeah, this is not a limitation of AI denoising technology itself, it's just a limitation of this specific implementation of NVIDIA AI denoiser as specifically stated in the NVIDIA documentation :)

Nevertheless, it would be interesting to see what halucinations this optix implementation would introduce in animation. Anyone eager to try? ;]

I will try to make something (just to see what happens) with the next build.

Overal looks like nvidia gave us something very incomplete, like *go ahead, test it*

About that, afterwards he speaks *even then the amount of computation required was amasing, 200 000 000 cpu hrs * Wich means that they made and used it

And some more info from Disney page.

Quote
Specifically, the team used millions of examples from the Pixar film Finding Dory to train a deep learning model known as a Convolutional Neural Network. Through this process, the system learned to transform the noisy images into noise-free images that resemble those computed with significantly more light rays. Once trained, the system was successfully able to remove the noise on test images from entirely different films, such as Pixar’s latest release, “Cars 3,” and their upcoming feature “Coco,” even though they had completely different styles and color palettes

Tho it is not clear was the output used in live release or not.

And i wasn't right about fiding dory, they used output as a reference for AI

somehow i cant get Optix dll working.. I installed custom with AI Denoiser checked. I even installed twice where i then got messages that everything is already installed and skipped.

I have a GTX 1070Ti.. any ideas?

disable your antivirus for a few minutes and re-install, avast blocked the corona installer for me this time, usually it only gives a warning.
uninstall corona completely then reinstall it

8-15 build DR server no longer runs at all, says on all nodes every time you try to run it "the procedure entry point could not be located in the dynamic link library"

It's working as expected for me, can you try clean install of Corona? I mean delete the whole Corona build from your PC and install it again.

15.aug. build
inside red rectangles is nvidia denoiser, outside is corona denoiser. Both amount 1.0.
1min. rendering, 3pass, GI/AA 4, LSM 1.0, MSI 4.0, adaptivity off, UHD cache
In this example nvidia is better(texture sharpness, env., curtain rod), except reflective surfaces and some parts of tiny geometry like kitchen doors, which are better in corona denoiser. So definitely interesting :)

Yay! Its working fine now. Actualy it is amazing the image below it just single pass.

Tho there is somehow difference in between how image looks in viewport and how it looks on output.

UPD - I was woundering why the flor is is blury and i think i know what to do to make it show detail faster. It looks like OPTIX denoizer uses data from normals renderpas to retain texture structure data and since my flooring texture didnt had any bumpmaping except for the round corners map (wich i think is not seen on the normals layer for some reason). Lowe the extracted Optixes normal layer.

Still cant get it working... the AI Denoiser doesn't even download properly. Also tried the latest installer 2018-08-15 with windows antivirus disabled.

I know what is the problem with floor and blurines.

Normalmap for some reason does not see round edges. I made slight geometrical chamfer and the result got a lot better.

(I pushed a contrast on normalmap for obsrevable difference.)

Also i attached an image of floor without chamfer on it with a reasanoble amount of pases to compare.

UPD - i cheked the original image with round corners. Actualy it is there on normal map, but it is very slight tho the values are the same .5 mm for both geometry and round corners.

PS - Overal i am enjoying it. 20 mins on 2xX5650 xeon for 1920x1440 image. Even setting amoint of denoising to 1 does not reduce detail much. (T3)

Nekrobul: In my example I was not using any bump map or normal map or reflection map on floor(simple polygon), just diffuse, so it must depend also on something else.
