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🔥

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!

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 Big Thank You. Wish I found this a few days ago. Took me about 16hrs to render an animation. (In chunks luckily)

tiles size changing helped for me alot

[AfroSanaa]

Clear and precise instructions. Thank you!

[metycream]

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!

I LOVE THE CATS IN THE VIDEO. LIKED AND SUBBED CUS OF

[nksolh]

holy moly this is the most useful video about rendering faster🤯🤯🤯

[sshr]

the lil cats make me focus better and watch this video till the end

[nick_samyy]

i love the cats as well as all the tips

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.

Please keep uploading, your videos are too useful. Thank you!

[shaikhabuhuraira]

bro god bless uh uh dont what you have did for me

[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.

[ABMENAD]

wow thnx for the info i didnt know about 1.5 pixel keep up bro !

[cgnerd]

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!

Excelent Tips! and cute cats! Thanks for all the tips, works very well! and the cats deserves de aaww! By the way, one tip that help me to make renders quicker is turn it off the Denoise in teh Sampling panel and insted use a Denoise node in the Composite panel.
Thanks for sharing!
