The OptiX™ denoiser is based on Nvidia AI technology and it is integrated into Arnold for use with IPR as an imager so that you get a very quickly denoised image as you're moving the camera and making other adjustments. Let's get started

THANK YOU SO MUCH THIS VIDEO JUST SAVED ME. I've been searching the web for days because I can't find the optix denoise in my Maya 2023 and every search result only points me towards render settings but the problem is optix denoise is missing from my render settings and I couldn't find it anywhere. I did find it now because of your video and I would like to say that you are a legend. You deserve a sub!!

[@sarkamari]

So amazing to hear this. I don't get much feedback in general so a positive comment like this does make my day. 🤍

[@iCamSkiEz]

So excited for you take on the rendering / lighting aspects! Thanks for consistently uploading gread educational videos. I always watch but don't always comment but thank you so much it's really appreciated

[@sarkamari]

thank you for your very encouraging comment

[@miladmolaee1548]

I saw a lot of videos to find the best way of rendering in Maya, honestly, this was the greatest one. Thanks for your superb tips.

[@sarkamari]

Thank you Milad jan. Very kind🙏🏼

[@verena86]

Thank you so much! This video was great. I love that you made sure it's useful for the future (showing which version you have so we know it migth work differently if we're watching this years after), and even explained sliders you didn't find useful yourself (the clamps) so we still know how they work. Fantastic explanation, thank you!

[@sarkamari]

Great to hear🫶🏼

[@Tim_2060]

Even though I've been using this for months, I still learned something new! The only thing I don't like about Optix is the color clipping. Sometimes, It just ruins the look of a scene. You can even see it on the right side of this scene, on the windows especially. Still great Tutorial, and nice music choice.

Did you notice you CAN disable the clamping?

[@gianmarcosanseverino423]

Professor Reza!!! I love your tutorials!!!

[@sarkamari]

Thanks Marco. Appreciate it

[@DimaZagorski]

thank you a lot for that! saved so much time with it :]

[@sarkamari]

Glad you found it useful Dima

Thanks a lot Reza!!

[@lord_francio582]

thank you, my renders improved a lot !

[@sarkamari]

Glad to hear this

[@Glasseyyy]

Thank you so much. Alot of the other tutorials are already outdated and I couldnt find a single thing on optix to turn on the denoiser

[@sarkamari]

Main reason I made this tut. Thank you Glassey

[@MarcoStillSeasonsCattaneo]

One thing to note though is that aggressive denoising eats away details from the render. It's visible even in your render, chair and other areas loose details and have other issues. Usually denoising is used to clean the last 30% of the image

[@DragonEspral]

Hello, I from Brazil thx for tutorial!

[@shakeelshahid3145]

Awesome!

[@Mehdi_afshar]

Nice!

[@GENIUSGT]

What do you think of the new optix update in arnold 7? Supposedly reflections and refractions are sharper (but I've been getting worse results). Also you probably should have mentioned that setting to box filter gives better results in optix.

[@pinakisaha162]

Its very helpful.. thank you

[@sarkamari]

Great to hear. 🙏🏼

Great!

ty very much

Glad you enjoyed the video

[@suresh6689]

can you make the denoiser sequence render tutorial

[@vinaux]

is it possible to batchrender with optix denoiser?

I see lots of tutorials on this topic, but none tells you how to denoise lightgroups. You can't select lightgroups AOVs in the selection box. So how do you do that?

[@daniboiyy]

would this work for the cpu as well or does it have its own denoiser for the cpu?

[@sarkamari]

Hi Dani Please watch this one for CPU deniosing: kzbin.info/www/bejne/qoexaGObba14f5Y

[@MrPositive3D]

I get an error when I switch to GPU and it just won't let me render. :( I don't understand why?

[@sarkamari]

Go to the arnold link i have posted in the description of the video to make sure your Graphics Card is compatible

[@cloudjumper5324]

Hi Reza, lets say if I plan to extract 250 frames using optix denoiser, Do I have to do it one by one or theres a solution for a sequence? and yes I am now using GPU rendering as well at home got my 3060 Ti.... lol

[@sarkamari]

Hey Abi. You can render a sequence via attribute editor using optix

[@cloudjumper5324]

@@sarkamari appreciate it thank u!

[@abdullaharshak.n7870]

So whether it is possible to denoise combined aovs ?? Using optix??

[@agtgaming1917]

Do this works forbatch render having multiple frames?

[@sarkamari]

Yes. have already answered a similar question in the comments

[@NikitaGal31]

Hello! Please, help me to understand why when I choose any imager nothing happens? Like none of them has any effect. How to fix it?

[@sarkamari]

Might be GPU compatibility. Check the link in the description to make sure your graphics card /driver support Optix

How to render sequence render or batch render using this optix

[@sailandge7342]

noice or optix? which is better?

[@peterrandall6761]

is there a way to denoise the veiwport quickly?

[@sarkamari]

Not understanding the question i am afraid. The final render is what matters

[@peterrandall6761]

@SARKAMARI I turned on my gpu and used the optix denoiser, that allowed me to quickly denoise the viewport do I wouldn't have to contially render out my scene to know what it looks like.

[@hopeuroky]

I haven't post window how can I search them

[@shakeelshahid3145]

Sir, makes a tutorial on auto character lips sync

[@johnsmathew2006]

Sir Arnold render view not showing post option

[@sarkamari]

make sure that mtoa.dll is loaded via the plugin manager. also make sure to use maya 2022 and higher

[@vallinborel9439]

It is possible to use this in render sequence ???

[@sarkamari]

It is possible. For that you need to add seperate AOVs in render settings and enable use `Denoise with OptiX` via passes attributes wondows

[@vinaux]

Sorry I got my answer here!

[@vinaux]

a demonstration with the same scene why not.

[@GENIUSGT]

It's worth noting that Arnold recommends using denoice when denoising render sequences.

[@YamanPrajapati]

If someone Denoise isn't working, then you need to just update your nvidia card through GeForce experiance

[@sarkamari]

Thank you for the tip Yaman🙏🏼

[@cameroncouto4858]

This is definitely quick but one thing I noticed is that when I render out an animation, the animation is flickering. Does anyone know why that is happening?

[@sarkamari]

Are you getting the same result with NOICE denoiser?

[@cameroncouto4858]

@@sarkamari haven't tried that one yet. Going to do that next.

[@cameroncouto4858]

@@sarkamari when I use Noice, does it have to be with CPU or can I use GPU?

[@sarkamari]

Best is to use CPU

[@cameroncouto4858]

@@sarkamari Got it. When I do GPU rendering with Optix, I try to render transparent materials on a transparent background (png or tif format) but there is still a lot of noise on those models. The noise doesn't show up on the transparent models when I have a non-transparent background (like jpg). Any idea why?

[@jquintero462]

OptiX did not help for me to lower noise.

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