What's a check box 😮

So:
-increase threshold
-lower samples
-activate denoise
-double up resolution
On point 😂
@@davidkohlmann The detail is back! 😂🎉
In other words: Resolution increases the "area" to be rendered. Then you use fewer samples for each patch of the area. Then AI does the rest. That is better than decreasing the size of the area/patches with more samples. The AI prefers fewer samples of more area than more samples of less area. Very grossly speaking :D

Voila@@RorenMovies
With adaptive sampling, the amount of Render Samples and Noise Threshold don't work 'hand in hand', but it's more a situation of "whatever happens first. If you set your Noise Threshold to 1.0, you can set Render Samples to 20.000. The idea is that once the threshold is reached, Blender will stop sampling for that pixel anyway.
Likewise, you can set max samples to 128 and Noise Threshold to 0.001 and Blender will stop sampling after 128 samples.
The point of these two settings is to allow Blender more time to clear up demanding areas of the scene, while not oversampling simpler areas that might already look clean using few samples.
The game-like graphics in the video here might tolerate noise reduction better than a photorealistic scene would.
Thanks for this explaination
This sounds like a correct answer.
That's right, there's rarely a perfect one-click solution for all needs. The truth is that the best thing to do is to take a few key frames in the render and render with different settings, either in different slots and compare in real time, or to different files to compare afterwards.
I came across this video as an algorithmic recommendation, but as a camera hobbyist I can tell you the hardest part of doing low light photography is to overcome the desire to eliminate noise entirely. What matters is getting the chroma noise levels down, not the luminance noise. The former makes the photo appear to be smudged and cheap, the latter gives a sense of sharpness and authenticity.
Whattt I thought the noise threshold was for the entire frame
I don't even know what emotions I'm feeling right now....Thank you.
No problem, Iam happy if it was helpful.
I also noticed similar things, and I think the reason for that is the denoiser - it sometimes gets rid of details, and sometimes causes artifacts. By bumping up the resolution you give it more input to discern the details.
Yes, it's a bit weird but iam sure there is a technical answer for that. I think it's a calculating thing. If you have a high threshold the denoiser takes most of the data of the edges and the small detail you have.
If you go lower you have more detail in your render, but less enough to calculate correctly and the denoiser is confused, results in artefacts. And if you go less enough to have enough detail you have the "clearest" image.
So it's like a little cheat to increase the resolution and increasing the threshold. One negativ point is the datasize. If you double the resolution the size is around 4x bigger. That everybody should keep in mind.
But it's just a guess. We have to ask blender development 😂😂😂
@@davidkohlmann The reason I guess is I think something abuot how supersamling works. Like if you have a 720*1080 screen but then you play a 360p video on it, then the pixels in between will filled with kind of some guesswork. But if you have play 1920*1080 video on the same screen then such pixel colour can be predicted in a much better way cause there is more information available. I may have messed up some details and this is probably a really bad explanation but I hope this might have helped.😊
This does not sound like a correct answer.
Isn't this also how RTX cards work? Lower precision, denoising and upscaling algorithms for certain filters etc? We've come a long way from brute math on older hardware to incremental "good enough" approximations on much faster hardware.
that is because 1 pixel of a lower resolution image (say 720p) occupies the same area as a higher resolution image (say 1440p) yet having higher resolution have more pixels, therefore denoiser has more information to figure out how the denoised image should look like. basically kinda like more ppi (pixel per inch) you have, the better the denoising quality
I had to leave a comment for you David, because I tried your method on my blender file and my jaw dropped after seeing how much faster files render. Plus I can up the resolution and still get much faster render times than the original lower-resolution images. This is a brilliant find. Thank you for not keeping it to yourself and taking the time to share your findings.
I discovered this two decades ago in LightWave! The noise reduction is a God send and one of the things you can also do is switch off caustics and reduce the number of light bounces from the ridiculous 1024 to say 7, 3 would do!
on the lights you mean?
Ahhhh Light wave. Memories...
I still have a working copy of Lightwave somewhere. I first used to use it on my Amiga 4000/060
Holy crap! That's the best bit of Blender knowledge I've seen dropped in years!
Just tried it on a fairly complicated scene which was taking nearly 55 minutes to render (i9 64GB RAM, 3090 GPU).
It took 1 minute 54 seconds. No discernable difference in quality.
That's sick, congratulations
Yes. I had to fiddle a lot with it and couldn't figure out what happens and drove me crazy.
The reason why it is way better at low samples is because the denoisers were trained on samples that has adaptive sampling turned off. When you enable it, the denoiser cannot find the same patterns. These errors are multiplied as the sample numbers are increasing.
Thats nice to know. Merci :)
Another setting to play with to lower render times is the light paths option, by default its light bounces are setup as:
Total 12
Diffuse 4
Glossy 4
Transmission 12
Volume 0
Transparent 8
But, if you have no complex materials in the scene such as see-through glass etc, you can remove those bounces. There are articles to explain better because I barely understand the values. A word of warning, if you're using the principled hair BSDF it won't display right if you change these values, instead appearing far too dark.
Nice tip here, thanks, and another thing you can do to improve your render speed and I saw a lot of people doing it wrong is that if you have a good RTX GPU, you need to disable CPU in Optix section in system settings. People think that combining the power of both CPU and GPU will make render faster but this is not the case and this is totally wrong at this point if you have a RTX card like 3080 or even better 4080 or 4090. The theory behind this is that RTX cards have a feature called RTX acceleration which is specialized for raytracing and you need scene data to be stored in VRAM to make that happen. If you check both CPU and GPU in Optix section, then CPU comes in play and it requires data in RAM which prevents GPU to access data directly in VRAM then the GPU will not fully be utilized and RTX acceleration will be disabled on hardware level. I have a ryzen 3950x and a RTX 4090, by unchecking CPU in Optix scetion, I gain 2x to 3x speed improvement on average. This is one simple button click magic and many people just don't do that, if you haven't, you can try it.
Yes, it is true. I also noticed this feature last month. I disabled this option for my rtx3060 and it makes my render much faster
@@PoMkAc27 I just knew this accidently. I previously worked with Octane render engine and the community highly demand CPU support and the developers stated why they stays tightly with GPU only and explained the basics of RTX acceleration to us.
XD never thought about it and never tried it without CPU. Thanks man, I will try this too.
It depends on your scene. If you have a large scene with tons of verts, materials, light sources etc. it will render much slower just using the graphics card. In fact blender couldn't even render the scene without crashing on my laptop with the cpu disabled and I have an rtx3080.
@@andrewmcintosh9832 as I said above, the Vram size is crucial to RTX acceleration. You got crashes mostly because of 3080's Vram size is 10 or 12GB, if you render from 6 to 8k res with a lot of textures, then you would see crashes very often. But with 24GB built-in Vram, 3090 and 4090 could handle much better and if you render with 3090, you would probably not see crashes so often. Also, you may need to check the GPU driver, studio driver is always preferred over game ready driver and sometimes newest driver may have some bugs or stability issues. But other than that, optix mode will render much faster than CPU mode
As a blender newbie just trying to take in as much info as I can this is one of the most helpful videos I've come across so far!! Just wanted to say thank you for sharing
my render time for a car model went from 7 mintues to just 23 seconds. That was really helpful.
Nice to hear that.
There are many options on how to optimise the scene. You did it nicely.
Also consider temporal denoise feature included in blender. It makes animation even better by removing denoise flicker.
there is turbo tools addon. That makes rendering even better and faster worth the money and time.
Uuh thats also a great tip, thanks for sharing this too
what is that turbo tools plugin? I would like to try them. Now I have jobs that consume a lot of rendering time.🙏🙏
K-cycles works fine for me! I must render often 2 images for vr and with not much samples you get much detail!
For twmporal denoise, is that the optix or intel denoise? Is it something else? Haven't heard of it
@@njdotson seems like, as SouthernShotty said in his video about "secret cycles denoising feature", this option is only for Optix
This really worked for me! I rendered it without this method and it took at least 2 minutes but with the method, the samples stopped at 32 with a 100 max sample and it rendered out awesome. Thanks for the assist 👍😁
Low noise threshold give better quality with less noise but it also create stripe of different noise level. Then the denoiser can interpret these as important detail and keep them and it makes the image worse. So when you go to 0.5 threshold there is more noise but it is even and the denoiser work better in these condition.
Also the min samples... If you leave it to 0 then it automatically render a lot of sample before starting to test for the noise level. So it can waste time on part of the image that are already OK. So it is not a bad idea to test with a low number to see if the quality is good enough. This can sometime cut render time even more.
You just saved me so much time on a project I need to output 600 images. Amazing. You are the man.
In my case I never adjusted the "min samples" values, always used the 0 value. And now I did a test and configuring the min samples to 8, this speeded my render a lot. (30%)
Wow, going to try it
@@chileaus I did a test now in Blender 3.6.1 using Cycles and only CPU, the default cube scene with default settings, render with 36 seconds in my computer. Changing only the Min Samples to 8 the render time now is 22 seconds.
Man, i’ve been looking everywhere for a video like this. Thx a lot!
THANK YOU SO MUCH!!!! i try all the other people setting and try to tweak but still not work, but this time I try to follow u, n it take me one minute for single image!!!!! My work became easy thanks for your video!
Wow, this is amazing!!! Nearly can't belief the improvement. Many thanks.
Omg dude, my individual PNGs with transparent backgrounds were going to be 16 minutes each frame. They are now about 10 seconds at 4K and they look really good. Thank you!!!
THANKS! This actually works!!!!
I have a store with shelves full of hundreds of items. What took forever to render is now 75% faster to render.
Brother you saved me 😢 because when ever I tried to render a heavy project either my Laptop dies or my blenders goes to heaven but now it's working fine and quick 😮
THIS IS INCREDIBLE! Thankyou David!
By far the best rendering method of blender in yt
Yes, and you can also do something like 0.05 to 0.1 and 4096 samples (to avoid to double the resolution and min samples 16), with ODIN and after a pass of OPTIX temporal and it's good. Nice video.
Thank you for your tips too. Appreciate it if other people can add additional informations 😊
ODIN?
I would advocate for doubling the resolution anyway. In my own tests, doing so and lowering sample count had way better image quality for negligible performance differences, even after downscaling back to 1080p it looked significantly better than natively rendering 1080p.
@@ExplicityDesigns It's the Intel open image denoiser.
@@Jofoyo Normally I compute with the preset I wrote upper the half resolution and upscale the result with AI.
Wow, that's a great tip! My 3D PC is old and slow, and I mostly render things for previews. This will improve it a lot :)
noise treshold is only used for optimization, it just disables render on certain part of image that noise level lower than treshold.
you can disable noise treshold if you render equally noisy at any part, and set something about 250 samples. noise treshold evaluation is consuming some computational powers itself.
Sometimes 64 samples is cleaner than 1024 with high noise treshold with same time.
and use fast denoiser also if you want maximum render speed.
I've found that putting the render samples at 300 - 500 with a noise threshold of 0.1 with denoising at 1080p produces very good results
I do this, also i make the frame range 2 steps, then use Flow frames to fill in the missing frames. Results look pretty dang good.
this sounds genius, I’m going to try this!! thanks
Nice one
Thanks for this awesome trick!
My render went from 5 days to 2 and a half days
Lol
This is mostly my preferences too
Threshold: 0.5
Max Sample:256
Render 1080p and scale up
Render 24fps then I use Flowframes for Interpolation to 2x framerate, it smooths the animation
Nice, thx for sharing additional informations. I will try it out too.
i recently also started to use flowframes to get from 30 to 60fps and it makes everything super smooth. it's funny cause i had installed it a while back ago for exactly that, but then totally forgot about it ^^
Thanks for the video, it definitely helped with a project I'm working on. I did some testing, and this synergizes with Min Light Bounces and the denoiser in the compositor. It adds a bit of time (in my scene, 29 to 33 seconds, down from a 3 minute full render), but the quality is dramatically better. You don't need to go any higher than 5 on the min light bounces, and the denoiser should be set to accurate.
Pro tip, every time you double the resolution you can quarter the samples, and if you combine this with the Turbo Tools addon, you can actually use around a 3rd of the samples you would otherwise need, allowing for a further 3 x speed up👍
I love Turbo Tools, and often use it with the technique shown in this video ♥
@@virtualviews8271 Awesome, and with Turbo Tools, you don't actually need to double the resolution to get good results fast, but like you say, Turbo will always allow you to use around 3 to 5x less samples in most scenes, no matter which rendering techniques you use 👍
@@3d-illusions Disclaimer: You are the maker of Turbo Tools.
@@0zyris yep, it has my name and profile picture on the addon and all videos 👍
Man I gotta get back to Blending. Your tip reminds me of the quirky settings in Stable Diffusion (making acceptable compromises for average GPUs). Kudos for finding this workaround. Lower render times are a game changer!
This is actually insane. The crazy long render time was one of the main reasons I quit
totally agree - might pick blender back up after moving on to unreal due to blender's complexity to use and most importantly, the 'eternity' to render even short clips..
this is because the instructions say that this parameter is responsible for when to start eliminating noise in the picture, i.e. if the minimum value is set, then the noise is eliminated immediately during rendering, and when we set 1, the frame is drawn first, and the noise is eliminated later
I just tried this tonight (after waiting a loong time to get my new memory and GPU) and getting to a point where I wanted to try a proper render. I rendered a butterfly model with HDRI for lighting and background at 2K resolution I think or double whatever it was at and used the 1.0 noise and 1024 samples. It rendered in like 7 seconds. Was large and looked nice. I used only Optix GPU, no CPU. So... I don't completely understand the best ways to do various things but this seemed to be very fast with only a butterfly and sphere and HDRI and nothing special like volume etc. thx!!!
Thank you so much brother, i thought i would never be able to render a proper 2 minute scene on my pc, but now i know i can!
this helped. minor quality loss but nothing I should worry too much about
Thank you for this video bro for real. Just took my render time from overnight down to an hour for a simple render.
i have one tip that will increase realism... make the windows less shiny.. just walk out on city and you will notice that window lights are way more dimmer.
Yo, your render and project look amazing !
Here would be an advice about the composition for the "colors/lighting" that you DONT HAVE TO take, it's just something that i thought of...
I think it would look even better if it was more bright. what i mean is that the image is really really dark and it would probably be insane with puddles to equilibrate the lighting between the top and bottom of the image...
Anywars, great works, it looks insanely good
Hey man, thank you 🙏
Also for your words and of course it's maybe a bit to dark. But iam not done yet and I will keep your words in mind ❤️
Appreciate that!
If I understand this, This is kinda what I do for still product renders - very low samples (less than 16), strong denoise, very high resolution (10,000+ px). Gets me a pretty fast render.
For my short, low budget renders, I usually up the samples a bit, and just turn off noise threshold. It works for my use case.
I love hese kind of tweaks I did not know about this. simply use the densoise check and set up the rest in the compositor to compress my render time enormous.
Wow, these videos are necessary if you're into blender, good video
i keep coming back to diese video, it's great settings! thank you for making it
Another tip from me: I may be stupid and this is a well-known fact, but when you render, it actually tries to render also in the viewport. So before you render either you turn away from your scene in the viewport or you check "Lock Viewport" under the "Render" button in the toolbar.
If you set your viewport to render view, it will render this too and will slow down the final render a lot. If you just stay in viewport it will load each frame, but without rendering.
But yes you should disable this to render /load your frame faster
I render from the command line. It seems to be between a 1/4 and 1/5 faster rendering from the command line.@@davidkohlmann
Damn, thank you... I was struggling with render time with an animation just like you. I was going to render it like in 3 hours. But now i am able to do so with higher res but 1 hour
1:25 Doubling the sample count usually doesn't double the render time but quadruples it. That's because the sample count is PER PIXEL. If this was true in this case it's because of the threshold.
True, it was just in this render example.
But if the number of pixels is the same, then doubling the sample count does indeed double the amount of work, and hence the render time.
But there's the same number of pixels...
WOW...I changed it to 0.25. Saved me over an hour!!! What is this nonsense
God bless you man!!❤
This info should pop up the moment you open blender or more people will use unreal to render stuff
i did this as well for the last few weeks, increased my productivity in blender that now i'm running out of ideas because of how efficient it is now lol
Lol that's one downside of course 😂
🥇 David, I did not believe you at first. I tried it on my end, oMG 😳. In fraction of a time, my render was finished. Thank you for this video.
I also couldn't believe it when I typed in the high threshold. I mean it was a mistake and I just watched my screen and my brain tried to figure out what happened 😂😂😂
Thanks Bro you saved alot of time!
I have an avarege configuration and this detail was really very helpful... Great thanks👍
it damm works... :O of course not gonna lie if u watch super carefully like in interior you lose some sharpness etc but the difference isnt that much and you need to compare them carefully which is 20 mins and wich 30 seconds :O this is LIFE CHANGING
I THINK another idea about noise is when you render with more light (like a camera pic during day or bright light) you get less noise SO since you control the light in 3D, set up your scene lighter at first (yes, you'll hate it) then render. THEN in Photoshop... just push the values back down and no noise. Just an idea. Maybe I'm wrong!
You are not wrong, thats basically what big studios and filmproductions are doing every day xD
But i would use blenders compositor instead. I did a video about it (not to push down the lights, but to archive a cinematic look out of your raw footage)
@@davidkohlmann Some people do their post tweaks in photoshop. I don't know blender enough to do the composite part inside blender. I'm still baffled by all that node business. I've been messing around with Blender for about a week and watching stuff a week or two before that and the tutorials are really helpful but it's hard to remember it all. Like.... I modeled a butterfly and left it symetric on the Z axis (for no good reason) and then later I posed it all rotated then realized it's insane trying to model with all kinds of rotations on legs and wings and antenna. Better to leave it flat till you know you're happy then pose it, I guess. well, thanks for the video. I added hair to my butterfly body but after coloring it black, it renders in cycles as gray. in evee it's black like it should be. I wonder why it's gray in cycles. ?
True Blender is pretty complex and if you don't use the tools often you don't get used to it and it's kinda overwhelming. But 3d programms in general are quite difficult... Even if you use one for years you still don't master all functions.
To your other problem with the hair in eevee and cycles... Eevee is not as accurate as cycles especially if you use particle hair. The grey color is probably because you use the wrong material for your hair (the printable bsdf sucks for hair) . There is a hair bsdf I guess, this one is much more accurate.
@davidkohlmann hmmm. I will check for that. The hair looks amazing tho even if it's gray. Heh. I will research more. Man, if it were not fir the tutorials and example stuff... it would be much more daunting than it already is. I don't even know what BSDF stands for.
@davidkohlmann Just did a search on the internet and yeah. It looks like blender has A special BSDF for Hair. I'll check that out tomorrow. Thx!!
I can't belive my eyes!! THIS IS AMAZING, THANK YOU SO MUCH! 😭😭
this changes EVERYTHING
Großartiges Video, ich wollte immer Animationen rendern doch es hat immer ewig gedauert. Bei einzelnen Bildern war das nie ein Problem so lange zu warten aber bei ganzen Animationen mehrere Tage oder Wochen zu warten und dabei nichts an meinem PC machen zu können war die Hölle
BRO!!! You saved me!
I do not know how to thank you for this video it was spending from me to render a photo 2 hours but after this it took just 2 minutes thanks sooooo mush
Amazing brooooo you just saved my life.Thxxx
Man you just save me a lot of time in a project I was working in!!!
Holy, you're a damn lifesaver. Cut down my rendering time on my 30 second WIP animation from 18 hours to 14 minutes. Goddamn. Thank you.
I did Lego animation that took like 3 minutes every frame now it’s take a 1 minute. This saved me from leaving my PC on the Whole day
Thank you. This is very applicable to my current project.
Thank you for the tip! Can't wait to check it out
It helped me so much, thank you!
Great, hoping making a complete tutorials ou workshops in the future
Thank you so much. I am a filmmaker and enjoyed watching your animation but wanted to offer this thought: While your camera angles where quite exciting they totally give the game away that "it is not real." No "physical" camera can pull off those moves and thus the illusion is lost. Yes, you can get all of those beautiful angles, but only by cutting between different cameras. You could improve your result just by cutting in the edit, it would be much more convincing and thus more exciting. Lots of cuts is what makes our eyes flicker, it excites us. Thanks again for the tip on render times. I will be trying that today.
I'll keep that
I just tried your settings for rendering and the result is excellent. Many thanks. I went from 5 minutes down to 1 minute on the frames I am working on with no quality loss. So I could now double my sample rate and still be less than half the render time!!!!!! @@davidkohlmann
I would also think it is similar to what has been said. Have you tried to deactivate the denoising to see the result ? The noisy version is of course better with a lower threshold and as you know, denoising "cancels" the generated noise and leave the details as they are ;) It might not fit every situation (like an interior for example maybe ?) Thanks for this great tip ;)
Since there is a basic denoise function (i guess v2.9 or 3.0) i never rendered without denoising the image XD
So maybe i should try it also...
I did a lot of interior in the past with blender too. I never had a problem with render time in this cases but every saved minute is worth it. I will try this also :) Thank you
This method worked very well for me, thank you.
You can also use tilling rendering with 256px, it'll be even faster, 'cause the GPU will render 256*256px individual for about 12 times for a output of 1920*1080px image and not the all image at a single time which will be more consuming for the GPU and slower the render time.
Wow! This is eye opening. Thanks
danke sehr david! geile animation!
I'm lucky to find your channel ...
🎉🎉🎉
greatest blender video on earth...
Hahaha found this out a long time ago, blender increasing the image size is so much more useful than increasing the sampling, the sampling and noise reduction queues are just clouds!
I always found rendering at very high resolution to be more effective than increasing samples
Also if you're rendering an animation, higher fps tends to make the artifacts look more like just noise which isn't that bad depending on the scene so it's fine to use less samples for 60 fps and more for 24
Thank for sharing ! this will save me so much waiting !
I just took 4 days to render a 13sec animation... had i known this before i would not have suffered so much!!
Feel you😂
0.5 noise threshold and 16 samples left the chat
Thats a really strange and extremely cool animation
I found this myself recently, very cool
Looks amazing!!! And also thanks fro the tip.
I don't know why, but everyone complains about these rendering techniques or always wastes their time on path tracing in blender, just to achieve a realistic look. But why don't some people try using UE5? It has at least Lumen with ray tracing and looks almost like path tracing. Why don't people give it a try?
Because UE5 us made for real time rendering, like eevee, just better. This is used especially for games.
Don't understand me wrong UE5 is very powerful, much stronger then eevee but not as strong as engines like cycles, if you want to archive a realistic look.
My example scene you can render also in UE5 fore sure. But that's not the point of the video.
Cycles and UE5 or other engines are made for different use cases. That's the main point I guess.
Maybe someone should make a video on comparing blender (cycles and eevee) with UE5 🤔
@@davidkohlmann Yes, I understand you. I also use Blender with Cycles, but whenever I do, those annoying noise artifacts always appear, giving the rendered image a strange effect.
It's a very experimental process to avoid noise in the image. That's why I think UE5 is better in this regard, as it takes less time to render and doesn't have those strange artifacts.
It would be really cool if UE5 could merge with Blender, similar to what happens with Maya. Well, I just wanted to express my thoughts like that.
And yes, there are a few videos that make comparisons. ua-cam.com/video/0L5Ssj6gW5o/v-deo.html
Probably because of Eevee... people who want to render fast are most likely using Eevee with some screen space plug in for the Global illumination. It is not as good as UE5 but it built in. That said render done with UE5 pop in my recommendation pretty often and these often use asset made with Blender... So telling that people dont use UE5 is not really true.
I agree that UE/Lumen is way better than eevee but I think UE has a bigger learning curve to set everything up. No only you have to set everything in your scene, characters animations etc, You also have to set the lighting and render in the movie queue. its not that simple.
i did as you told and my render time went from 7 minutes 52 seconds per frame to 1 hour 51 minutes.
I don't have a complex project but the images are over 800. i doubled the resolution, noise threshold to 1.0 and samples to 300, and then to 1024. Denoise also checked.
THank you so much, it saved me from a lot of headache
I don't have an RTX yet, however I was able to speed up render very well with CUDA and GPU compute.
love it, watched 10 video yours is the best
This saved me so much time! thank god for you man
The reason why I made this vid 😍🙏
I am curious though. How is the temporal stability?
The problem with too much denoising is that across frames, it may look "shaky", so to speak. You might have a static object that looks like it is shimmering.
That's why I increased the resolution. It avoid this problem in most cases.
I am using a GTX 1060 6gb But for some reason it ALWAYS heats up and takes Years to render and when I hit Cycles The whole device is on life support although from the videos of people using it they look like they are not having trouble..it runs smoothly fine…now it’s not issue in the GTX 1060 itself it’s not damaged or anything i just don’t know why it doesn’t function well maybe I have settings issues or the Processor Isn’t good enough (it’s i7 gen 8)
Hi, David. You have discovered the mind blowing technology of AI denoising! As the image gets noisier, the denoiser does more work. Until finally, it does all the work. I'd be eager to see your finished animation. I would assume it doesn't look nearly as good as a still image, with a lot of flickering, is that right? Likewise, I don't think the technique would hold up in a more photoreal render, like another commenter pointed out.
Sadly, you can't really cheat quality in a path tracer quite yet. While AI denoising is amazing, real sampling is still the way to go when you need high quality.
Hey✌️
Yes, you are right. In my last video I talked about rendering with potato PCs xD and also a bit about the downside of this technique. Commercials are one of them. If you want you can watch it.
klasse´muss ich gleich mal probieren. Danke
It's extremely strange that you're getting less noise at a higher threshold, unless like someone said the ai was trained on specific profile.
Yea thats what conused me and the reason why i wanted to share this.
@@davidkohlmann I can't replicate this, I set noise threshold to 1 and my render acts exactly as expected, takes 12 seconds and is a little blurry from denoising. I'm still testing though, maybe it's specific to the kind of scene you have?
Hmm don't know how your scene looks. Maybe you need to increase the resolution even more. But take care of your disk space if you do so.
I am sure it will work for most renders.
very nice technich. it is improving tons of rendering time with x2 resolutions.
I have to say I am in shock about this technique. I did a try and before I did 4K 256 samples in 90 minutes and now with the same quality in 8K 1024 samples with the Noise 0.5 it took 22 minutes! same final quality!
made 4X less rendering time.
thanks again!
