My render time has reduced drastically with seemingly no difference in quality and so I am really grateful to you :)
Amazing!!!!
Turned my 23 hour render to 2 and a half hours Thankyou so much
So glad this helped!
This is an excellent summary some really useful technics. In particular I found for a complex geometry nodes animated scene I am working on with some moderately complicated materials that render time was being killed by initialisation. Enabling Persisting Data dramatically reduced my render times from ~30 seconds/frame down to about 4-5 seconds/frame.
I can't thank you enough, this really works. I went from 2 hours to 20 mins THANK YOU!!!
AMAZING! Glad this could help!
thank you for all the tips !!
from 1 hour to 3 minutes with same quality Thanks I am really grateful to you
thank you very much ! I really needed this !
I came across this randomly. I was having difficulty with getting my renders working. Thanks a lot, very helpful
I'm glad this was helpful!
Thanks so much for all the info!!!
No Problem!
You are a legend, Tysm 🤘🏻
Clear your cache too. Render at size. Get a separate SD like Samsung on a thunderbolt connection. Backup your hard drive. Do low rez test samples for animation. Render while you sleep.
These are all awesome ideas too! I actually do the low-res samples alot as well. Haven't tried clearing the cache, how do you do that?
My render time changed from few hours to few minutes! Thank you for the tips!
Love to hear that! No problem!
Will it possible to render 10sec clip in less than one hour . Iam using asus a17 and 3050rtx
@@prraneth-skyop1374 Totally depends on your PC specs what what it is you're rendering, so many factors.
Thank you so much this helped so much with flips fluid renders
Had to come back an rewatch this gem !
Thank you for the great tips!
THANK YOU! I'm new to Blender and this was very helpful to me! :)
Glad to hear this helped you!
Amazing, it was very helpful all this information.
Thisis very very helpful/useful.
Thak you so much !
This tutorial has sped up my renders by over 60%. Thanks for posting it.
I am so happy to hear that!
Thank you for this. It was really helpful
No Problem!
thank you bro!
Thank you ☺️❤️😍☺️ thanks a lot for your help
Thank you very much for this informations. Realy important for me :')
So Glad this helps!
thnx, man! usefull!
The man’s a life saver 🙏🏾🙏🏾
so nice , Thanks
Thanks mate
I found this really very useful particularly as I have a relatively low spec graphics card. Thank you for taking the time !
Of course! So Glad you liked it!
Thank you for good tips!
Another tip - hide all objects on viewport ( click A and H )
Great idea!
Nice, very informative
Thanks buddy! Subscribed
Thanks for the sub!
Very Helpful thanks Kenny!
Thank you for the kind words Natr!
Thanks!
very helpful!
Thanks a lot ,you change my life
These are some great tips 👍
Thank you help a lot
thank you so much! i was working on an animation but it took way to long now i can do it in 3 hours instead of 7 thx
So happy to hear that!
Great tips! Thanks.
No Problem! Glad you found them helpful!
You just saved my life. Thank you so much!!!!!!!!!!!!!!
No problem! So glad I could help!
Thanks so much
No problem!
I just textured a whole motorcycle IN render mode before I looked up and realized that I was actually in cycles I thought I was in EVEE the whole time It looks so nice now on a RTX 3050
damn this video is amazing. cant wair to try it on to my next project
Awesome! So Glad you love it!
Thanks
great one, great tips!
Thank you!
Thank you
For GPU rendering with RTX cards, you want to select Optix mode and uncheck CPU. RTX cards have a feature called RTX acceleration which will increase the speed for path tracing. However, RTX acceleration requires scene data to be cached into VRam instead of Ram. If you check CPU in Optix mode, then CPU needs scene data stored in Ram which will conflict with RTX acceleration, and your GPU usage will go up and down and it will never be fully occupied during rendering process. I have tested that and by disabling CPU, my render speed can be 3-4x faster. And another things is that you probably need a GPU that comes with large VRam otherwise when Vram is full, the data will fall back to Ram which will slow down.
i love you man
Bro lots of thanks it really reduce the time from 8 hours to one hour bro❤
Glad to hear that!!!
step 4...uncheck the cpu, I've got a 3080TI so it's close to your 3070... found out my cpu was bottlenecking my renders, my scene went from 2:32 to 52sec, persistent data was awesome. Thanks for doing this!!
No problem!
Thank you SO MUCH! These tips are probably the most valuable that I've learned. Until I applied them, my current project took over 18hrs to render. Now, it takes under 2hrs. Adding motion blur and depth of field, and boosting Render Samples from 32 to 128 jacks it up to 4hrs, but it's still much better than 18.
Thank you very much, it is incredible hahaha, time rendering was changed from 100 minute to 2 second $$$, Thanks a lot
No problem!~
I went from 2min/frame to 10s/frame thx!
Amazing! So glad to hear that!
Also disable cpu in optix device, as gpu rendering alongside with cpu is actually slower, then just rendering using gpu.
good stuff
Thank you very much. I was wondering why a 3 second animation took 3 hours to render, managed to squeeze it to 15min. Thanks again👍
No problem! Glad this could help!
Great tips..can you please talk about how to make perfect glass material that shows whats behind smoothly
I'll add it to my tutorial-suggestions list!
Being a novice, wouldn't have known all these. Hope i won't have to undo these settings. Liked & Subscribed.
aditiv rendering hope this will come up....
thx hope some test Part 2 come up.. maybe 3.5..path guiding, a, the beta Subdevidon surface resolution ... etc. older versionen check...too
I really hope "persistent data" helps with the flickering I am getting on finely textured walls etc, it's quite deflating to go to so much work and be let down by the video.
Yes I have heard of this flickering issue before, it's always tricky to fix!
Thank you for this tutorial!
What about creating a similar video, but with tips for increasing viewport FPS while animating?
Love it! You should still make it, that sounds super useful @Fuad :) I'll watch it! Post the link under this comment once you upload!

@@KennyPhases I meant you could make this video, if possible. I'm a complete novice with Blender. Sorry 😂
@@Fuad_First Omg oh!!! Yeah I will add it to my list of tutorial ideas!
Helpful information ❣️❣️
first 3 suggestions were like captain obvious and was ready to walk away but then the rest of the video helped me reduce my render time by 5 folds. thumbs up.
Thank you!
So how does this new pathtracing feature apply to cycles x existing? does cycles x make sense anymroe?
my rendering from 15mins max per frame to seconds! Wow! 🙏
Amazing glad to hear it!
I have the same CPU. HIgh FIve!
what a beast.
Thank you for this nice tuto amigo, just a question please, does it make a difference in rendertime if you apply the modifiers or not?
Yes absolutely! If you have a ton of modifiers that will 10000000% slow down your renders!
Sorry to follow up, if you DONT apply them, it will most likely slow down renders more, definitely worth applying or limiting the amount of modifiers in your project!
Bro. No!!!!! Sir. You are a lifesaver.
When rendering while the viewport animation is in render cycles, a black screen appears. All my lights are on. Why does cycles happen when Eevee doesn't have the same problem? What's the problem?
Not sure without looking at a screenshot, message me on Instagram and I will help you there!
hi, i don't have the stop viewport icon, where i can find it?
You might need to expand your window a bit more! It's usually in the top right! You can always switch to "solid mode" as an alternative to this!
my gpu compute option is greyed out and only uses cpu for renders
help?
Message me on Instagram and I should be able to help you, you might want to check your preferences and SYSTEM, to see if you have your GPU enabled
For making 3d animations, and renderings in blender , i currently have a 6600xt would u recomend me to go for a 6900xt or a 3080 or 3080ti? i think nvidia is better right?
Nvidia is good all around! I'm no PC-Nerd, but I would always suggest the 3080, 3090, 3070 etc!
@@KennyPhases tyvm yea i was thinking one of thoose 3 !
Hey! Why is it grey when I select gpu compute?
Not sure! Same thing happened to me actually! But GPU should STILL work don't worry! Must be some weird glitch!
Yea mine always has that but it still works lol
I am wandering HOW to keep those settings permanent? I always need to re-adjust them. If someone knows the answer....
You can save a "default file" with your favorite settings by going to File > Defaults > Save Startup File (once you have your settings the way you want them). But be careful because some render settings won't work as well with other projects. There is no one-size-fits-all. So keep this in mind!
@@KennyPhases thanks for answering 💡
Is it like the same for animating ? Or there is some other settings to do ?
This works on any frames for animation or just still-images!
@@KennyPhases Thanks, i've tried it and it's going really well ! You've gain a new sub
One time I changed light passes from 32 to 64 and somehow 64 was either same length or a small bit shorter
At a certain point you will stop noticing a difference! There's a "limit" where you stop noticing any increase in quality if that makes sense. Kind of a threshold area.
@@KennyPhases yeah I know :) I’m just saying one time I did that and I’m pretty sure it somehow took less time. Also I feel like high render passes is most noticeable if there is either glass (or something like that) and if there is volumetric fog
what do you think about turbo render v.3
Sounds cool but haven't tried it! Can you link it?
For some reason I've never used the time limit feature. This could actually be useful for me when I just want to make test renders in under a certain time!
Awesome! Glad you found this helpful!
Hey man I have a favor for you.
Can you do Blender benchmark 2 times and tell me what’s your score?
I will add this to my list of things to cover in the future!
@@KennyPhases Thanks man! I’ll be waiting 👍
can you define "changes in your scene" because i cant help but take that literally which means it wont work for animations period
in preferences> system >cycles settings says only "none" or "metal".. there's nothing else there.
Sounds like you're on a mac-device, choose Metal!
@@KennyPhases yes, thank you so much
step 2 should have been step 1. :) thx for the tips but you didn't compare denoise option. I found that setting the denoiser to optix instead of the open image one vastly reduced my render denoising time. Also, for me, it seemed that putting the noise threshold of the render at 100 times yours (ie, 1.0 instead of .1) and then DOUBLING the output resolution (I render usually 4K or 3000 something by whatever. Double the 1900 setting that matches a normal 4K TV ratio), also reduced the actual render time. Seems paradoxical to ask Blender to process DOUBLE the amount of pixels and get a faster render but... that's how I have been doing it. You have more pixels to work with and thus... a denoise threshold of 1.0 should work and take less time than using ACTUAL resolution (half) and .1 threshold. ? Just what I find that works for me. but maybe that won't work for every kind of render. What do I know? Nothign! :) thx
Wow this video turned 14 minute in 6 seconds
Glad to hear that!
It was never clear to me "Total" max bounces actually mean/do? total bounces of what? diffuse, glossy?? whats the point, if you set diffuse to 10 and total to 2 for example?
I believe you can set a lower "total" and it will average out all of the light-paths, but to be honest I'm not entirely sure! I think you can adjust the value to experiment with what works best in your project!
It is somewhat literal. If you set glossy to 3 then place 4 mirror then the light will never reach the fourth mirror it will stop at 3. Same for transparency if you set it to 2 it will literally turn black a the third layer. Same for diffuse if you do a maze place one light then set it to 2 then the light will never reach the wall after the 3rd corner. Each time the light touch something it is a bounce even for thing like transparency. Each bounce add to the total but it can bounce on different surface type. Let say you make a path with mirror and windows and glass. Then the light may traverse 2 windows then bounce on 2 walls then reflect on 2 mirrors. It is a total of 6. Let say you use a total off 4 then the light will not reach the last 2 mirror because it has already reached the total. And then if the transparency was 1 then the light would have been stopped after the first window then never reach anything else even though it is far from the total allowed.
Hey dude, congratulations for your initiatives!
Have you ever tried to use BAT RENDER?
I'm not sure if it reduce time of render, but is very useful and easy to make a render queue.
Create a .txt file and "PASTE" this:
cd "C:\Program Files\Blender Foundation\Blender 3.2"
blender -b C:\XXXXX\ZZZ_01.blend -a
blender -b C:\XXXXX\ZZZ_02.blend -a
blender -b C:\XXXXX\ZZZ_03.blend -a
cd "C:\Program Files\Blender Foundation\Blender 3.2" - is where your blender is installed
blender -b C:\XXXXX\ZZZ_01.blend -a - this is the location of the .blend file you want to render - and you can put many files in sequence (but dont use space needer special characters on names or folders)
Than, save the file as a .BAT file.
Run the .BAT file and blender will render all your files.
(sorry about my english)
What do you mean by “ blender will render all your files “
@@SalwanSameea This is a way to render different files in a sequence... is a render queue - is very helpfull to render animations. For example, you have 5 animations in 5 different blender files to render. By using this "method", your computer will render all frames of 1st file, than start automatically render the frames of 2nd, etc..
Programs like 3D Max, or even Keyshot have this resource, but I've never found it on Blender.
Sorry about my "poor" english, and if you have doubts, let me know.
@@mariognypekfilho3899
Thanks, yeah you mean blender projects , like if i have 3 seperate blender projects then blender will render them all using the method you mentioned.
Please what is your GPU or Graphics card Spec?
GeForce RTX 3070 TI!
@@KennyPhases great
"Want better renders? get a better pc" xD
i mean it's true!
"Total" just means that the highest number will be used.
Example Diffuse is 2 and Transmission is 10, then when you select a number of 8; the render will use Diffuse 2 and Transmission 8
Total is just a quick way of choosing your preferred amounts.
Thank you so much. My render time on a test file reduced by a factor of nearly 2 pi 🤣
AMD users: use HIP and select the appropriate devices (I actually need more help in understanding how it works but I had to make sure to only select the GPU and not the CPU so it runs faster.)
True.. I personally tested the optiX both GPU and CPU checked. It's slower than just GPU alone.
Great stuff save my 7hours to 1hr
Happy to hear that!
brother, você pode fazer bruxarias com esse plugin Turbo Tools V3 para Blender, faz um teste e me diga o que achou!
Really great tip, I turned a 25 minute render to 33 seconds
That's amazing! Did you utilize most of the tips or was there one in particular that helped?
It's that good
Damn I gotta watch this
Dude was just rendering a cude with 10,000 samples
What if my GPU is sucks? :/
Time to upgrade!
@@KennyPhases But, I still don't have enough money. You just said " Upgrade", is too easy to say... 🥲🥲🥲
@@cg.man_aka_kevin I know parts are very expensive but if you're serious about 3D-Design, Animation, etc... you have to invest in yourself to succeed! Otherwise, these tips and tricks will still significantly reduce your render time regardless! If you want my full-setup you can check it out under my story-highlights on Instagram!
@@KennyPhases Okay!
Really good tricks to save render time. But i hate it that everybody asked for faster render time, but not for better quality. If you do archviz for example like me, i can not use this settings. With a lot of 4k textures and denoiser on, you loose a lot of details. Even if you render with 1000 samples. Everybody should remember that lower render time is lower quality.
Long story short: If a client pay me 300,- i turn denoiser on.
If he paid me 1000,- i turn it of to get the highest quality possible.
The same with noise thresshold, light path setting and so on. 👍
Agreed, definitely can loose quality quickly when you want to reduce render-time, it's a balance that is tough to achieve depending on your project-timeline! I am always about quality over everything, but sometimes a balance can be achieved if you play with the settings enough! I find that denoising sometimes destroys the render every now and then!
you wrote Rednder 4.3 in your description instead of 3.4.
Fixed Thank you!
I need blender in Android Phone
Edit: Blender 3.4 version is cooler! Can you show me how to download blender, These memberships are annoying me, I can't download it with membership!
Whoa, I never knew that Blender is already at version 4.3
1:52 I wouldn't touch the samples IF u have an RTX GPU. It makes a difference by 1 sec from 4096 to 50 and THAT rly don't matter. And in my case, my textures are high res, so i can see the difference. But the other Tipps are great. Thank you!
Thanks!
