I'm here for the cats
Me too 😻
😂
came for the blender tutorial i will never use because i will never have the free time to actually use blender, watched it a second time for the cats
Did these tips with my 4090gpu and now my scenes render before I even start modeling them. :)
tile size and persistent data is just what i needed. thankyou sir🔥
ive been using blender for over two years and this has helped me a lot
Dude, what have you done to my computer? Normally it was taken 42 minutes to render, bcs of you it rendered in 20 seconds. I owe you. God Bless you man!
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 :)
Thanks, man! You helped me a lot. My project used to take 50 minutes for one frame, but now it only takes 10 minutes.
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!
These tips are just general guidelines and they are meant to be tweaked if your scene needs it
@@BadgerBricks 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 😅
Excellent Tips Man. Especially for fast moving animations if any quality is lost. Just done 2 renders. 1m15s and cut it down to 40s with no observable loss in quality.....A Big Thank You. Wish I found this a few days ago. Took me about 16hrs to render an animation. (In chunks luckily)
Dude thanks, short and to the point
Persistent data only works for scenes where the only animated property are camera properties. Animated objects or materials etc will not work.
amazing tips Badger! love it
dude your underrated,keep it going❤
the lil cats make me focus better and watch this video till the end
Please keep uploading, your videos are too useful. Thank you!
Great 🔥
This video help me😊
Clear and precise instructions. Thank you!
Glad it was helpful!
Really helpful tutorial! Thanks
Cool tips, thanks a lot!
Just in time! I need exactly that information!! Thank you so much! Niceeee ^w^
Thanks ❤
In Blender versions after 3, it is recommended to leave tiling off, as Cycles is optimized to render without.
Where is you been all my life ? 😍
genius
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.
Great video thanks. Personally I just use the Turbo Tools addon, it's Turbo Render feature is like black magic for speeding up rendering and removing flicker from animations. I'll definitely try some of these tips in combination with that though!
This is a perfect video, great job!
Thank you very much!
@@BadgerBricks Honestly, the quality made me think it was uploaded by an account with a huge following, so I was surprised! The video just popped up in my recommendations :)
thnx bro appreciate it
Thank you !
Thank you so much bro I have the gpu memory problem too
Good tips when I'm trying to render on my GT 630
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.
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.

1:40 After cycles engine update, if you have enough vram it is better to disable tiling at all for speed. At least for my rtx 3060
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.
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
I render to 1440x2560, QHD gives more details than FHD but it's more time efficient than rendering 4K. With a little adjustments in Photoshop renders turn out nice
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.
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.
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!
I am not sure what's wrong then but maybe this will help: starts at 2:50 ua-cam.com/video/hXIHCzZJD5g/v-deo.htmlsi=AEfCrJkpU9RT4RsR
It is about animated noise, maybe you have it turned on or something
@@BadgerBricks 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!
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.
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.
@@BadgerBricks Thanks for your response. Love the video btw. Keep at it bro
Watched also many "Render 90% quicker"-videos and have to say that this is the best! Knowing most of this and thinking same about noise treshold/resolution (easiest is to write 200%) etc, but something new came here also!
I have to try this vram-tip, will it work so good. Bought earlier better GPU because this was the main problem, now I maybe can use also other pc with less GPU memory for rendering, have to try.
Hoping that somebody who have also Turbo tools-addon would answer that is there any help when samples are couple of hundreds and noise treshold is like 0.1 and upper? I bought it and hoped best, but getting quicker renders without it. What would be settings for this addon for get best results? All the time in versus reviews there is sample rate something like 4000 and that why addon make it quicker. But when sample rate is 150, is there any way to get same results quicker?
Thank You and ✝️ blessings from Finland! Channel ordered!
8:00 what about using after effect blend option for missing frames?
I am not sure how this option works but if you think it might work you can try it :)
how can I tell blender to render one frame each two, so I can do the interpolation?
set the frame rate in the output tab to half of the desired fps
It worked like magic...thanks! I am having issue rendering out a scene though....am I doing anything wrong?
I can't really tell yet, can you give me more details about what is happening, like maybe some error pops up or something?
@@BadgerBricks so when I render a single image the render window pops up and renders so fast but when I render a sequence the system isn't spitting out any files...I am trying to render out a scene...sorry I'm new to blender so excuse my poor terminology
@@ihassan1001I guess you need to set up the files to be saved automatically, you do that by going to the compositor tab on the top of normal blender and turn on nodes and shift a to add a new node called file output and you connect it to the render layer node and then choose the folder you want to save and it should work. You can see it how to do it at the end of my batch rendering tutorial. You could also do that in the properties tab under the render tab on the right side.
@@BadgerBricks you're awesome! Thank you so so much!
hi, is it enough for heavy 3d vfx project rtx 3060 12gb?
or i should go for higher price gpus?
i earn money hard, so i need to know it is okay or not.
and if it isn't enough, tell me which model is good at higher range around 700 usd for example.
gpu: gt1030 2gb,
cpu: i5-13600k.
I think the 3060 is ok, it depends for how much will you buy it but it should be great and be enough. If you have more budget i would go for the 3070, in my country it goes for about 300usd used or 3080 ti for 450 usd used or if you want futer proof it more you can go with the 4070 super but it is the same as the 3080 ti but newer and pricer for like those 700 usd. you can alslo look for 4070 ti because it is quite a bit better. and also around 700 i think. I personaly would go with the 3080 or ti becouse it is the best value imo and it was the top card of the 30 generation. the 3060 if you would get it for like 250 usd would be a good deal and you could upgrade it in future if it wasnt eoungh
here is a list that i made recently with all cards and the benchmarks in %. 100 usd is around 400zł
RTX 3060 ti 8gb - 1100zł 130% used
RTX 3070 8gb - 1300zl 148% used
RTX 3080 10gb - 1700zł 190% used

@@BadgerBricks amazing answer. Thanks a lot 🙏🌹
I have 1050 & I know the struggle. At least it's small, compact, cute & energy efficient xD
Wouldn't recommend AI interpolation for low-framerate or cartoon animations.
how i can make fire in blender ( my pc shitft )
Tbh I have no idea I have never tried but there has to be a tutorial about it on UA-cam somewhere :)
Great video overall. But ngl some of the tips were a lil misleading. It would have been nice to see you try these with an actual complex scene.
8:47 .. At the cost of quality
Cats!!😅
Cats! cats! cats!

The question is if flowframes collects data
Frame interpolation software generally doesn't collect user data. However it's always good to double-check the privacy policy :)

you like cats huh
gtx1050 WTF !?!?
i got a not used 1080 ill would send it to you. but maybe some one got a spare RTX.
please send him a used RTX !!!!
what's up with the nasty ai generated cat at 1:25 ??? oh the whole image is AI generated... come on :/ the same one again at 4:04...
You found an ester egg and you are first probably, like 20k people watched it and nobody mentioned it👏🏻. It's on purpose, normally ai doesn't generate such bad images but I wanted it to be glitched like that. I might as well have used a stock photo but i thought it would be funny to have a glithed cat
Light tree tip is false.
I don't know man, for me it helped reduce the time. You can watch this video, it covers this topic more in depth ua-cam.com/video/LLTgujPphF4/v-deo.htmlsi=orjSE9hi-VOw6ZFj
@thenodecamp Please tell me the true way to adjust the light tree, I want to compare.
