Denoise with Arnold (NOICE) in Maya

[@PJ-pw7tw]

Sin quitar méritos a otros canales que explican muy bien el proceso, creo que este vídeo es uno de los mejores, con resultados gráficos increíbles. Sencillo y bien explicado. Muchas gracias.

[@sarkamari]

Gracias por tus comentarios positivos. Me alegra que hayas encontrado útil el vídeo.

[@reaktorleak89]

That's pretty good, I think it's worth a try at our studio again.

[@ikechukwunwanah4902]

A very big respect to this turorial. I do appreciate

[@sarkamari]

Thank you🙏🏼

[@meetvyas3469]

Very noice video

[@sarkamari]

Thank you

[@SamuelVogel-n5d]

Did anyone else have an issue with no file appearing after hitting denoise? I am trying to denoise a test frame using an exr file with all the same render settings as the video but after clicking denoise no new file appears, and my old one is unaffected. Any solution would be appreciated!

[@lylevillanueva8624]

This is very NOICE. Hahaha thanks a lot.

[@sarkamari]

Good one 😂

[@DimaZagorski]

Useful as always, thank a lot!

[@GlenGramling]

Hi @sarkamari I'm following this video as closely as possible, I have also read the Arnold documentation asked in reddit and discord, and I still cannot get this to work. Can you help me figure out what I'm doing wrong?

[@sarkamari]

Are you seeing all the tools and attributes ir you’re not simply getting the denoised image?

[@GlenGramling]

It was acting like it denoised the image, and outputting with no errors but the result was not denoised. I even tried it through the command line with the same result. Eventually through trial and error and much frustration I got it to work by adding an RGBA AOV and adding a variance filter to it. It was sort of a hail marry but it worked! Thanks for the response! @@sarkamari

[@ThanhVan-fi2lw]

wow!! amazing

Hey, do you know of any way to make noice (or any other desnoising imagers) work with region rendering? It denoises each region separately, so when you join them, there are artifacts at each tile edge. Is there any way to make it work in "camera space" instead of "tile space"?

[@GENIUSGT]

What do you think of the new oidn denoiser?

[@sarkamari]

Works better in terms of "ease of use" but I still prefer NOICE

[@gregfoster126]

Do you not feel like you loose detail using denoisers?

[@sarkamari]

Did not tweak the settings much in the video so perhaps I did :)

[@javibonfort3324]

Hi, when I try to press denoise, literally nothing happens, I don't know what happens, if you could help me please.

[@juancamilomanotas1513]

I have the same issue. Have tried searching around with no luck. Did you find a solution in the end?

[@sarkamari]

Please note that in Maya 2023 or higher imager_noice does not support temporal denoising (required for denoising an animation). Also, It is recommended to add imagers before starting an IPR session. Denoiser imagers should be applied before post-processing imagers if the post-processing is introducing new features in the image (ex: bloom). You should apply the imager_light_mixer before any denoiser imagers, as light AOVs won't necessarily be denoised by the denoiser. For single frame simply run Arnold Denoiser: help.autodesk.com/view/ARNOL/ENU/?guid=arnold_for_maya_utils_am_Arnold_Denoiser_html

[@diegoalehandrourso1063]

There is a lot of conflicting information on "Output Denoising AOVs". The Arnold manual says that checkmarking the box "Output Denoising Aovs" is all that is needed. Other users claim that is not enough, and that all aovs need a second output driver set to "variance" I spent about a month figure it out and I am still left with doubts... Do you know the truth? HELP, thank you.

[@airiharuki4432]

I try this and my PhysicalSky background vanishes, everything glass and sky renders black black. Would you be able to help?

[@kartonique]

The same

[@sarkamari]

Use transmission passes to capture more information and comp in post. Not a good idea to denoise everything at once

[@nightcoreempress5248]

Thanks!!!

[@achimschnick4890]

Very very usefull. New witth Maya and some astonished, that it obviously does not like GPU Renders IMO. Camera AA screwing up makes me mad. And Denoising always looked crasy bad to me. But this Tutorial is really worth every Minute to optimize Denoising, so that it looks ok. Thank you for this. Heard Autodesk has an IRAY Render Plug in too. But only on additional Costs ;-(

[@ts.haniffaiqmohdhashim919]

really appreciate with this video tutorial sir. I got one question.. usually i render my file with png sequence and the size of one image was around 1mb.. i tried to follow your video tutorial and render it to .exr.. it turn out the size of the image is around 50MB. is it normal the size is that big? got any other way for me to reduce the size...?

[@sarkamari]

Yes. Unfortunately exr files are heavy because they carry so much information. Actually that amount of information allows us to tweak and denoise each frame.

[@sparkyel]

Thanks for tutorial, I was hoping it would work, but to be fair it dubbled the rendering time, and denoiser doesn't work for me for some reason, and I can't fix it

[@sarkamari]

Try the imager_denoiser_noice when rendering a single frame: help.autodesk.com/view/ARNOL/ENU/?guid=arnold_for_maya_utils_am_Arnold_Denoiser_html

[@migi847]

If I have render passes and Light aov's and I want to denoise the EXR sequence before taking it into composting, How to do it so the Denoised exr's will still have the passes in the exr ?

[@sarkamari]

If you're taking them into comp you can also 'denoise' and 'degrain' in comp too (using nuke)

[@TheBigMaxo]

Hello i try with a bit of SSS on my mesh it remove the noise but create rainbow effect

[@sarkamari]

Have you tried increasing the SSS samples in the render settings?

[@TheBigMaxo]

I found just need to add the SSS in the AOVs@@sarkamari

[@sgiff]

The real need I have for increasing speed is for animations or sequence. Is it possible to use the Arnolds new denoiser for doing animations? The old one (using Maya 2019 sp3) with the default Arnold that ships with it. The version I have is not stable for doing animations. It creates noise between frames.

[@sarkamari]

Yes you can. Just send the frame range to anything you want via the Render Settings window and run the sequence through the denoiser

[@duendetattoo75]

Thanks for the tutorial but when I aply the denoiser jump this error ; invalid literal for int() with base 10; do hoy know what is this?

[@sarkamari]

Seems like you have a Python issue. Try using the top Input box (select by name) and type defaultArnold* www.screencast.com/t/coRH9ALA3

[@cameroncouto4858]

What is the sample rate of your HDRI light? Do you keep it low?

[@sarkamari]

It's the amount of noise.and yes With NOICE i keep this value low.

[@cameroncouto4858]

Ok. With mine, after I rendered the exr and applied Noice, it didn't smooth the noise at all. Could I render it with CPU and run noice as an imager at the same time?

[@cameroncouto4858]

@@sarkamari Can EXRs render a transparent BG? Also, Noice isn't working when I follow your instructions. It still has noise.

[@sarkamari]

Exr is a dynamic file so depending of the software you're importing it to you have a choice to bring transparency. As for the NOICE make sure the supporting aovs are added and play around with the settings when you in the frames through the denoise. It should work

[@cameroncouto4858]

@@sarkamari Nope nothing. It's no big deal. I might stick with GPU rendering.

[@triplea7383]

thanks the tutorial ,but why i after denoise the picture lost aov?

[@MITE2994]

Why not use GPU???

[@sarkamari]

Good question. I have another tut to explain the GPU workflow. Best to know both ;).

Poly count of this scene sir?

About 30k for the whole scene

[@samueldang4265]

Can I do this with .tiff files?

[@sarkamari]

Sure can. Any high bit depth extension is preferred (tiff 16-bit or exr)

[@janjanas6644]

Can I use denoiser to denoise my Normal AOV instead of my RGBA beauty?

[@shadowcasterstudios4042]

you should be able to attach any Imager to Any AOV

[@themoodswinger8139]

i think to reduce the noice by using camera samples in large scenes make reder time consuming

[@AndresMagnone]

Yet another example of Maya being a complete piece of trash and me scratching my head bald wondering how this pile of fecal matter is industry standard. It doesn´t work. And as usual here, the explanation seems to be "just cause". I did everything right, step by step, and when I hit denoise it gives me an error saying "error in line 10" and I´m just supposed to sppend 3 hours of my remaining 12 until delivery time fighting Maya until it magically fixes itself. I guess I´m spending my limited time complaining in a youtube comment section, might as well use it to fix it and then unal1ve myself.

I am sorry but the Optix and this technique did not work for me.

Please check the compatibility and your graphics card (link in the description) also check you Maya version

this is work only for Beauty pass how to denoise Aov light passes Like Diffuse_direct_Key

[@sarkamari]

If you have LPEs I highly suggest you to use compositing apps like Nuke for denoising and degrading.

[@adekunlekadelu7873]

Lets debate this once and for all. Between blender and maya, which is good for rendering? Which one is fast? Which one wont give you noise headache.?

[@sarkamari]

You’ll get 200 different answers from 200 biased users. I certainly have my own opinion working at Disney but as soon as I say I prefer one the other 100 users start the debate. Think about which one works for you and/or the company you’re working for
