Did these tips with my 4090gpu and now my scenes render before I even start modeling them. :)

[@Monkeymario.]

same but i have a rtx 3060 i want a rtx 40xx gpu sometime not cuz its faster but i just want nvenc avi and hopefuly blender adds nvenc support in the future oh also i almost never use solid viewport i always use render until the scene gets too complex and laggy

I have a 3050 💀

[@viipeditz]

@@akashnikalje6553 3060 is good enough according to budget ⚡ it has 12gb vram that makes it unbeatable at this price go for it , 4060 has it's own supremacy but not in the case of vram so go for 3060 if you make big scenes ✨

[@corex1464]

Really nice edited video! Here are some thoughts i had: -Blender has a built in addon that you can activate that auto determines the perfect tile size -The pixel size (or filter) also works as a quick anti-aliasing afaik so dont just crank that down to get higher detail -The higher noise threshold is good for scenes with large smooth faces. In scenes where there is detail and you want to see stuff like grime or fingerprints those will get smudged into a blob too For anyone starting out or never have looked into optimizing your render speeds id recommend to get a sample project and try to change all the stuff people on the internet tell you works. Try all possible combinations. Then try to understand why what changed, had how much of an impact. For example, you have a scene with a lot of glass but the focus is imagery in the back and reflections of the glass. You can disable light refracting which will save a ton of render time. But if you want a realistic "light casting through Waves" effect youll need the refracting. Understanding stuff like that will enable you to optimize Blender for every scene you could ever do. And dont be scared to fuck shit up. Thats what you have the template for :)

[@CriispyWaffle]

Heyyy i was wondering if you could tell me where to find the built in addon to auto determine tile size??

[@corex1464]

@@CriispyWaffle First comment got deleted for the link. Basically beginning with blender 3.0 it got removed since CyclesX made it obsolete. You should still be able to use the Tile Size manually if you encounter low memory (not sure if they meant vram or ram). So either you use blender pre 3.0 (which I wouldn't recommend) or you test around with the Tile size manually if memory is a problem for you

[@SaschaUncia]

Feedback: - Persistent Data can cause weird issues in some scenes and increases vRAM use. Best to try rendering a few frames with it on and off during final render to see if your scene benefits from it. - Tile size exists to save memory if I remember correctly. In some cases the cpu can benefit from very small tile sizes, I'm not sure if this is because it lets the CPU use a smaller CPU memory cache instead of system memory, someone may know more. On GPU however, you should use a larger tile size such as 1024px or 2048px unless your card has low vRAM. User tests on forums generally indicate that the smaller size tiles will actually slow down GPU renders, although if your having trouble with the larger tiles, 512 is still valid. TLDR, start large on GPU and only reduce if it is helping, otherwise keep large if you have the vRAM. Increasing it past 1-2k has diminishing returns on most GPUs. - Pixel Filter (Pixel Size) is used to prevent harsh aliasing in renders. The optimal setting may vary from scene to scene, but between 1 and 1.5 is a good range. Rendering at twice your target resolution to downscale after will probably get you a better looking result than messing with the pixel filter. Agreed on light tree, it increases render time and memory usage greatly in some scenes and can actually add noise. Leave it off by default and try enabling it for final render to see if it helps or hinders your specific scene. It can be useful when there are many mesh lights.

[@jungwon8906]

Damn you're my lifesaver!! Also such a great edit with the catssss 😍😍

[@M.Scibor]

Noise treshold is REALLY important and in dark scenes going above 0.02 will result in shitty image. I'm now rendering scene on 512 samples 4k and with 0.01 Noise treshold and scene doesn't seem so diferent then one on 4096 samples but some of your tips are useful. Great video!

[@BadgersStudio]

These tips are just general guidelines and they are meant to be tweaked if your scene needs it

[@M.Scibor]

@@BadgersStudio Okay, you used language like "You have to" LOL but great video I've been using blender for 4 years and I had no idea about some options 😅

[@gottagowork]

Persistent data can cause adaptive subdivision microdisplacement not to update between frames, so it's one I'd be aware of. I'm very skeptical about reducing pixel filter. Can get nasty. Remember that sharpness and details is lost to denoiser as well. I recommend rendering with less samples but at double the resolution (4 times longer), then input and output sharpen in post.

[@Allie-w1l]

I've been learning 3D graphics with Blender, and finally tried to use its video editor to combine a ton of old video clips that I had in my PC.

Thanx a lot bro🔥 it’s really helped me from around 2hr to 1 minute

[@GabrielJFreire]

Really well made video and helpful for those of us with a less powerful machine. But a couple of considerations, you can go even lower with pixel width setting (to a minimum of 0.01 if I'm not mistaken) for a really crisp image, but be aware that changing it around may increase the amount of aliasing in your image, especially depending if you're working with a small resolution. My personal feeling is that it acts almost as a Temporal AntiAliasing seen in games nowadays (TAA), which you can look up and see comparisons of it on and off, the lower the pixel width, the more definition, with the cost of more aliasing. Another one, and this is a helpful one, you can actually increase image resolution WHILE rendering with almost the same performance. Say you set your render to 4K with a resolution scale of 100% and 4096 samples (just an example, it doesn't need to be this demanding). You can set the resolution percentage to 200% and then divide your sample count by 4. So I'd render at 4k, with 200% image resolution, but with 1024 samples this time. The reduced sample count makes up for the performance cost of rendering at a higher resolution. You can re-scale it afterwards within Blender itself through the compositor, image editor or even with MS Paint. Also also, I'd advise against going too high with the noise threshold, it may make you image look like an oil painting sometimes as the denoiser tries its best to average the sparse sample count for each pixel. Usually I'll set the number of samples, then set at least a min value of samples correspondent to 1/4 of the max samples, so 100 max samples, 25 min samples and so on.

[@senserinka]

[@moonstrobe]

In Blender versions after 3, it is recommended to leave tiling off, as Cycles is optimized to render without.

[@True-VFX]

Persistent data only works for scenes where the only animated property are camera properties. Animated objects or materials etc will not work.

[@yaxoz_]

This is really helpful tutorial, thanks. Is one more thing that will speed up the overall work in the blender and can affect the rendering speed. If you have a lot of RAM memory on your pc, click: Edit->Preferences->system (scrol down)-> Video Sequencer and you will see Memory Cache Limit. Set on 8 thousand or if you have many RAM, set 10 or 12 thousand. I have 12 thousand, when I have havy animatioin or I work in vfx, 12 thousand speeds up worki in blender.

[@Disent0101]

wouldnt making the pixel size smaller undo a lot of the performance gains? good tip though, it explains the blurry renders even at max settings.

[@BadgersStudio]

I don't know, I think the pixel size is more like how the image is processed at the end like denoising and it doesn't really change too much

[@Disent0101]

No, it's rendering each pixel, so if you decrease the size of each pixel, it needs to render more pixels to fill up the same pixel dimensions

[@BadgersStudio]

​@@Disent0101isn't it what resolution is doing?

[@Disent0101]

@@BadgersStudio there is resolution and pixel density. I assume the 1.5 pixel size is essentially creating less pixels to fill up the determined resolution, and then upscaling them to the final output, that's why its slightly blurry.

[@Disent0101]

so if it's 1.5X pixel size, its essentially creating enough pixels for an image that is 75% of the final output, than upscaling them, hence the lack of quality.

[@mattburkey]

Given that your graphics card is from the GTX era, you may find that CUDA is faster than OPTIX in many circumstances. I had a renderfarm of 1070's and in most cases they were slower with OPTIX than CUDA. The only time I'd prefer OPTIX is if I was including my workstations in the render farm as they have RTX cards and I needed the consistency, there are slight differences between a render result between the two modes. I've since upgraded my farm to 3060's and Optix is much faster by comparison. If you're rendering a one off image, increasing the noise threshold and using denoising it a great way to save time, but rendering an animation with those settings will result in a very temporally unstable video that almost looks like an what I would liken to an animated watercolour painting.

5:50 you need to keep it set to the processor which is CPU because when you set it to GPU it will want to use the graphics card that the MacBook doesn't have. After reverting to CPU in both the side panel and preferences menu, the rest tips should still work and speed up the render. Let me know if this resolved the problem or not? Rest of the settings should work regardless of whether you are on Mac or windows and also make sure your render engine is set to cycles not eevee

THanks for the video, so is it correct that lowering tile size does not effect the final quality of the render? I had been confused.

[@BadgersStudio]

Yes, tile size has nothing to do with the quality, it is about dividing the whole image into smaller sections so it is easier for your pc to process but it doesn't effect quality

[@tomcollins6989]

Great video. Thank you. Question. When you say increase the resolution. Do you mean render at a larger size? I’m familiar with photoshop and the ability to increase the ppi or dpi (print) but I wasn’t aware the detail can be dialed up within the image. If so, where are the settings.

[@BadgersStudio]

Yes, larger size. When you have an image already taken, you can't really increase the number of pixels without using complex AI programs. However, when you're taking a photo or rendering in Blender, you can choose the resolution (like 1080p, 1440p, or 4K). Higher resolutions capture more detail because they save more pixels with bigger file size.

[@tomcollins6989]

@@BadgersStudio Thanks for your response. Love the video btw. Keep at it bro

[@bazzahill6182]

Setting the noise threshold to 1 works best. Why? who knows. I find CPU vs GPU only makes a few seconds difference. A cheap way to halve render times, I built a PC using two salvaged Intel Xeon E5-2697 CPUs (from Ebay) and a ZX-DU99D4 motherboard (from Ebay) and some scavenged parts (inc a 1080Ti) for about £130 (expert knowledge required). Render times are about half using a 4060. Spatial Splits settings in Performance can make a big difference.

[@firstnamelastname061]

No that's a little misleading. It doesn't just "work the best". I mean sure for simple one product image (like shown in the video) the difference is hard to tell. But on a complex scene with lots of texture maps, lights you can ABSOLUTELY tell the difference. The image is fuzzy-ish because denoiser has to work extra hard to clean the image and guess the details. Increasing the resolution does help a little but ofc that costs extra time.

[@Arjjacks]

@@firstnamelastname061 It's probably not wise to treat a threshold of 1 as a one size fits all, but he's not actually entirely wrong about it's utility for rendering. For some reason, Cycles is at its worst around the 0.1 mark. You'll get the worst smearing and loss of detail from denoising anywhere from 0.08 to 0.3. At either extreme, weirdly though, this doesn't really happen. Like, sure, at a value of 1, you'll lose more detail than at 0.01 or lower, but the image doesn't liquefy the way it often does at the 0.1 mark. So, at least for me, I've found that a threshold of 1 combined with 2k or higher resolution, plus multipass denoising in the compositor, gives me the fastest and best results.

[@ComixProductions]

Im pretty sure turning it up to 1 is basically like the old Adaptive Sampling feature, especially considering Noise threshold in itself uses adaptive sampling.

[@Gantahat62]

Will these tips help with image noise for animations? Because my biggest problem is that no matter how much I increase the samples or reduce the noise threshold I always perceive a strange flickering in my animations. I've tried using both denoiser (Optix and OID) and even using the Denoise from compositing, I've even rendered in EXR Multilayer to remove the noise using a strange script, but I always perceive that problem and I'm not sure why. Anyway, I'm going to put into practice some of the tips you mention, I hope some of them will solve that problem. Thank you very much for the video!

[@BadgersStudio]

I am not sure what's wrong then but maybe this will help: starts at 2:50 kzbin.info/www/bejne/nomseXawj693a8ksi=AEfCrJkpU9RT4RsR It is about animated noise, maybe you have it turned on or something

[@Gantahat62]

​@@BadgersStudio I'm checking and I have it turned off, but since I'm already trying everything, I'll activate it to see how it responds. Thank you very much for answering and trying to help me!

[@Arjjacks]

What you're referring to is something called temporal instability, and I'm afraid Blender as it currently stands is poorly equipped to deal with it. Basically, because the noise pattern for each frame is different in an animation, the actual denoising results are also, consequently, different. So when you play all the frames back in sequence, you're seeing that differing clean up per frame show up in realtime, resulting in that flicker. There is a built in temporal denoiser in Blender, developed for Optix supported GPU's by NVIDIA, but, as I'm guessing you've discovered already going by the "strange script" you mentioned, it doesn't work very well. You're best bet at the moment is probably Turbo Tools. There is another addon, Super Image Denoiser, but I'm afraid it's bundled with a bunch of other tools now for a pricey few hundred Euro, so Turbo Tools is your most affordable option right now. I know Lukas Stockner is looking into adding temporal denoising to Blender proper, but that could be a long way off yet. Though smatterings of the concept exist in Eevee Next already, funnily enough.

[@Gantahat62]

@@Arjjacks Thanks for that answer! At least now I know the name of what is happening to me. Now, the thing is that I also got to use Turbo Tool, but since it requires a lot of pre-configurations that are a bit difficult to understand, I have had the same problem. Still, I really appreciate the answer, I will have to study more carefully how to use Turbo Tool and see if I can make it go away. That or directly just use Eevee Next for everything.

[@Arjjacks]

@@Gantahat62 Turbo Tools should do the trick, it might just take some tweaking of the temporal intelligence settings in the compositor. Each subsection is designed to handle various particular issues with temporal instability, such as fireflies, motion blur & depth of field, reflections, transparency, HDRI's, and so on. He has an about an hour long video on the various settings, it's probably worth checking out if you're still having trouble with it.
