Since we temporary solved that max crashing isue i can make some animation testings.

Le first one. 2 pases original resolution 1920x1080 rendertime per frame 8-12 sec with default settings and 100% blending with ai denoiser.



Lower is some frames from animation in full res to compare flickering.

I think it does not look bad at now already with that 2 pases but i think if i let it render atleast 1-2 min per frame result would be less *artistic*

I'm using the old .bat file trick to run 1.7.4 and 3beta on the same machine, but the 3beta install refuses to find the nvidia denoiser .dll's ("Failed to initialize NVIDIA AI denoiser: Unable to load required DLLs. Please make sure that the the NVIDIA AI denoiser Corona component is correctly installed."). I tried putting them in Max/plugins and the max root, but no luck. I don't want to run the installer, because I don't want to remove 1.7.4, so where do I put the NVidia files?

I finaly had an oportunity to test AI denoiser on long time render. (i forgot to switch it off on my work PC so here it is 1000 pases 1.8% noise =D)

Well, i cant say that it is magic wand or something but it for shure does not eat much deatail if the rendertime was proper (10-5% of noise)

Also it dealed with areas with heavy noise even without new solver (inside of building and on black semimat surfaces)

BTW it handles the heavy scene perry well i have here 17 lightmix layers and a total of 2.4 Bpoly and 350 light groups.

The images might look identical but there is still observable noise on non dinoised image in it IES lights areas.

IMO it is very suited for production.

About that new solver crash, i have replication scene and can upload it with instructions if stil needed.

AI denoiser is not meant for final frame denoising. Corona denoiser will always be much better at that. AI denoiser is low quality but fast denoiser mean for interactive rendering. I am not very happy about the way it was introduced in daily builds, because it can be used to denoise also non interactive rendering. Because of that, there will be some people nagging about the idea of it being removed and available only as IR denoiser, but at the same time, if it would not be removed and available also as final frame denoiser, then it will create huge amount of confusion because many newbies will think it's better denoiser than Corona and incorrectly use it.

What would be your suggestion then? I certainly wouldn't want that new denoiser would become exclusive to IR only. Although i agree that it has significantly lower quality than Corona's native solution, but sometimes quick and dirty denoising is just what i need.
I'm not Corona Team member. Everything i say, is my personal opinion only.

I don't know realy guys, it helps a lot in situations with a very little time and a lot of rendering to be done. It is like magic wand in some cases.

For example now i have a projekt wich i am carring alone and i have to make around 100 images in 4k the images will be printed on A3 and shown to 3rd party and know what?

The client is perfectly fine with slight artifacts as long as the image is totaly clean from the noise, and i have very complex light situation with a lot of shiny metalic surfaces with SSS marble etc all sort of stuff.

And for some reasaon that ai denoiser lets me to render image for 15-20% for a poper result, may be not that detailed as i wanted but still that is 1.5hrs per image not 8hrs and as i now hav only a pair of twin processor x5650 it counts a lot.

Image below is from this project.

Fine, but very visible artifacts especially on the ceiling part with decorations. Looks like unprofessional retouch in Photoshop
I'm not sure that this can be printed :)

It resembles the picture and in shortage of time it is better option than the crispy noise comming from all holes.

And is not that noticible on A3 print. In this specific case it is all that needed.

PS - do you really think that someone will be looking for render artifacts when viewing images for 2500 m2 baroque apartment trough one day?

Optix Denoiser should absolutely keep the same privileges as native denoiser. Use in any mode (Interactive or final).

Given that denoising is now possible during interactive, there should also be the same behavior as during final one, being able to blend on scale 0-1, very useful for both finding good compromise between light clarity and material detail while also enabling to turn it "off" sort of.
Give it a rollout or parenthesis description of "preview/low quality" if you must, no issue with that, but definitely keep them at same level of flexibility.

It is the best feature in long time and imho should deserve forefront attention. Absolute revolution for me.

Regarding it, do you guys feel like it works less once the rendering reaches certain amount of passes or time ? My GPU will spike to 100perc. during intitial denoisings, but then hover down.

I am completely agreed with Juraj.

Both are great, It is all about balance between amount of noise and blending % as seen above on the image with 1% of noise optix does not produce artifacts.

————————————

I haven’t noticed any difference on long time renders. But it struggles most with denoising after first pass. But I don’t have gpu performance monitor and can’t confirm that.

We'll see how it all works out, but I think with good education it can then be up to the user whether or not they want to choose it for final - so long as they know the shortcomings when they choose one or the other, then it seems fair to let the user (and their client) choose which is the best approach. We will definitely always recommend the higher quality of the Corona denoiser, which is more sophisticated in what it does and how it does it, and we will stress that in as many places as we can think of so that users understand what they are choosing between - but so long as a user is aware of that then it would seem ok to let them make their own choice. We'll listen to what everyone has to say on the subject, and will make a considered decision either way.

Would prefer the option for the User to be able decide on that manner. Stressing out better quality in the tooltips should be enough in my opinion.
Being able to cut render times in just previews (and delivering them in considerably higher quality, closer to the final look even despite some artifacts) is huge in itself.
Thanks for the good work.

BTW - any chance for roadmap update ?
