I tried the multilayer denoise in blender, but I noticed that it took like FOREVER to render a single frame compared to a single denoise on the beauty pass. even with the denoise node set to fast, it is still between 1 and 2 sec per pass to denoise! I think I would be better off (timewise) for a similar quality by denoising the beauty pass with just more samples. What do you think? at the end, I just recreated in blender compositor the 3 main passes (final glossy, final diffuse and final transmit), then denoised only those 3... but I am not even sure I gained on quality compared to a simple beauty pass denoise. I think there is a sweet spot in render time vs quality about that. I would love to see a video putting that to the test.
I wouldn't have even considered multi layer denoising so thank you. I do have one suggestion if you haven't edited the next video yet. Can you increase the audio levels? I was at max on the phone and it was listenable but still had to focus more. Maybe I'm just going deaf.
Hey when you have the file output at around 10:40 how do you get the alpha and other nine yellow node connectors to change those colors, when ever I add a input it just makes it yellow with no option to change it to anything else, will this mess stuff up? (Still watching the vid, havnt even used nuke before yet ) also on 4.1 rn
This was really helpful. I wanted to composite in Fusion, but I don''t have the Studio license yet, I still want to practice before I decide to buy it and the free version doesn't hve a good denoiser for 3D renders (not that I could find anyway). I was thinking of do the compositing in Fusion and then bring back to Blender denoise i, but it would be a dumb workflow. But no, being able to denoise it before in Blender and then go to Fusion solve my problem. Thank you!
Very cool video! but How come you said 5:21 the compositor uses only CPU if you can go to render properties then go to "performance" and select GPU device for the compositor? doesnt that works or im missing someting?
can I make node preset and use it across all projects? cause I see it is time consuming process. also would be great to optimize render time and combine this workflow with light groups to use them all together. anyway thanks for sharing this video.
Direct and indirect are different. You add them and then multiply by the colour to get them to look normal, there’s a blender wiki page about it for a more advanced description 👌🏻
@@ethdavis right, but you put the output from one single add node into both inputs of another add node. If I’m seeing this correctly, you multiplied the direct and indirect by the color, then added them together, then added that output to itself
@@SeeYouInBluffington Yeah, so after you multiply the colour, you need to add both passes together.And do that untill you have the final output. If you're curious why, just set up a scene and try it out :)
Awesome method and great video Ethan :) I am a blender & after effects user and have been for a while. But I learned on Nuke in school, but for my side it soooo expensive. I see that people have already told you about the audio levels. Still a great video tho!
Thanks! Yeah nuke is definitely expensive, I am an avid fusion user before switching so maybe try out that if you want a similar experience? It’s not as good but definitely good for the money! And yeah haha, thanks anything though :)
I know that I can extract the denoised passes after checking the compositing box in the property. Is there no way to skip the output in the property and extract only the file output in the compositing tab?
Nice, but on the multipass version you just need to denoise what's needed. Color, emission and environment passes regurlary doesn't need the denoise operation
Thanks Eduardo! Whilst that may be the case for most scenes, you need to take it as a case by case basis. Complex albedos and materials using emission textures will benefit from denoising for sure. Not so environments, but this can help bring everything into the same ball park of noise to add your grain after the fact.
Im trying to follow along.. but i cant find nuke script in desc. Could you please share it with us. Thank you for uploading this video. Looking forward for more of your content.
You could do it right at the very end by plugging the final mix into the glare node. You could also just plug the emission into the glare node and then add that by using screen at the end .)
@ethdavis Okay thank you, I guess the second option is better because I am rendering singles passes to export in davinci, so basically i connect the emission to glare, glare to mix screen and mix screen to the emission input of the output node?
Dumb Question…. So this seems amazing but if I don’t use volumes or translucency in a specific project for example, should I exclude those from this process, to save on performance?
I have a question, i render my animations with low samples , like 40-80, and then increase quality with topaz but it gives me a lot of flickering and weird artifacts expecially in the dark area like shadows, how can i fix this?
When you are still in Blender you put all the layer passes through denoise nodes. So they are denoised. But then when you're in Nuke and you do the temporal denoise. Does that mean you're denoising twice?
Nah, in nuke it’s blending the different noise patterns together so it stops the ‘flickering’ if you want to do the temporal denoise in blender, I reccomend watching the other videos I linked. I don’t use it because you can’t do the multi layer components
Oh I see, so when you output for Nuke you bypass the denoise nodes in Blender? In the Statix VFX video at 8 minutes he says that you can take the mulitpass version and feed it into the temporal average setup but he doesnt show the setup and so its not clear if he bypasses the noise in the multipass...
So essentially when I use Nuke. Everything is Denoised already in blender and I’m using the denoised layers in Nuke. The thing with the temporal denoising in blender, it only denoises the main image. So you lose the ability to rebuild the image back with the main layers. You can add them on top, but nothing else (like change the density of the fog
Yeah thats what I mean. Everything is denoised already in Blender and then when you take it into Nuke you do a temporal denoise on it. So its denoised a second time? Or am I missing something? Sorry if I'm coming across thick if I am missing something. 🤔
Hahah, no not quite. So what I’m doing is a form of “temporal denoising” which is blending the denoise patterns. I’m using a “vectorframleblend” node inside Nuke which is a bit different, it just blends frames together rather than denoising again. So it keeps all the same detail, just stops the flickering :) if you need any help with something, pop me a dm and I can help ya out
@ethdavis I sadly enough am not at my main pc for the weekend so wouldn't be able to right now. If you figure out the case with sev before then id like to know :D. Though even without it it already looks much better (and I can just apply the ao layer separately through editing software), great tutorial. 👍
Great tutorial but what if i want to output each pass to their own image to edit them later in Photoshop I tried to plug each denoised pass in to an output node but it didn't work

Interesting denoising workflow. I just used a single denoise node and rendered with a higher sample rate if necessary. Will try this out 👍🏻 But is it also the same render time including processing? I thought it takes very long with so many denoise nodes?
I am doing excactly as you are showing for the combined denoise but the outcome looks washed out . Is there anything that i might doing wrong ? I am also using my AO.
AO shouldn’t be added on. It is used to add more contact shadow so you would ‘multiply’ it. But you don’t need AO to rebuild the image, it’s an added extra
@@ethdavis Thank you so much for the help . I tried multipling it with the combine and actually got a good result but as soon as i added it to the whole composite the result came out noisy on some parts and i think it is because i used both combine and all the other inputs (diff . trans , gloss...)

Awesome tutorial thanks. I need help. All my EXR files are completely black. I am using blender 4.0 could you please guys help me? i followed the same settings as shown on this video :(
@@ethdavis hey , i am making an animation and i would like to add it to After Effects and when i do render in PNG i have the final render but using EXR, is everything black. Nuke, fusion i fo not have it unfortunately. 🙏🏾
Are you rendering in multi-layer? Sometimes if the software doesn’t know how to read them it may just be reading a layer in there that is completely black. There’s multiple files in a single EXR so that’s probably why. You could do your export as individual EXR files which should solve the issue but I don’t know after effects unfortunately. But definitely use EXR over PNG, so much better
@@ethdavis yeah when it does render i see the image . But when it is saved and let’s say i would like to open the exr file in Blender itself, the image is completely black and it is the same thing in After Effects
