Hi, it's a nice feature BUT I recommend to check this feature just before the final render ! BECAUSE I experienced that, if it's 'ON' , and you render some stills while working on the scene and you change for example the world HDRI, you won't see an update in the next still renders UNTIL you change something in the render settings, to force the cache to rebuild. So beware of, that the cache isn't useful, when still doing test renderings.
It is a beta version so there can be some bugs. I tried switching HDRis in a test scene, from a day light one to a night time one, and it worked in my test. If you find a bug you can report it
Sounds great, why wouldnt this feature be on permanently? Even if its off, rendering a frame would use the same amount of memory to calculate the scene for a frame, wouldnt it? So if its on, its going to use the memory also, but just calculate it once right?
With the checkbox on, it stays in memory. With the checkbox off, it's likely the data is purged once the frame is rendered. I'm guessing you wouldn't want it to be on all the time because if you have a weighty scene, it wouldn't make sense to have 2GB of data sitting in your memory doing nothing while you're just modeling and not rendering.
Also another comment mentioned that when you change certain settings, the scene needs to be rebuilt otherwise your cached scene will not reflect your actual settings. Seems like this feature is meant for when you're done with everything and are only in a rendering workflow
This is great! the only con that i found is that only works if the character or model dosnt have animation, if it does you will only get the camera animation, but not the character. Unless im missing something, of course. but when i tried it, that happen.
hello Christian, it is still in beta so there can be some bugs. I downloaded a mixamo character animation and imported the fbx in a test scene. It worked in my test. If you find a bug you can report it
Persistent Data is "Gamechanger" But on my unchanged object animation persistent Data not working all the frame they build scene and then rendering starts 😒 help me
From the description: "For Eevee and Workbench this option is not available, however these engines will now always reuse the depsgraph for animation and multiple view layers. This can significantly speed up rendering." I don't know how the depsgraph works but it seems even though it is not available for Eevee it is also getting a speed up.
Yeah I saw a big change in my render with 2.93.. the first time I try to render my animation of 250 frames it's crash after making only one image and the second time it's crashed after only render 5 images.. I can not see yet how it's can save me time if I have to look after it for his crashing ;-p
it seems to work when rendering on the CPU when I tried. After clicking on the persistent data checkbox, you must first render once to cache the render data, and on the second render you will see the speed improvement. Or maybe your scene has a fast scene build time so you can't see a difference?
Sorry im a noob. How do i increase memory to make the most out of this? Is memory the same as ram? Or is it how much storage i have? Sorry for dumb question
Hello this feature will use the memory of your graphic card if you render with the graphic card, and your computer memory if you render with the CPU. In the video it says "at the cost of increased memory usage" which means that the feature will utilize some of the memory when enabled. Not that you need to "increase the memory" like you asked. Hope it helps

When you hit render with Persistent Data, it looks magic cause it starts instant. Blew my mind
I like the fact they have updated the rendering system even for 2.93, despite 3.0 getting Cycles X which is going to be a game-changer.
I feel like this button has been in Blender for years and just hasn't done a thing. This is great
Yeah, that button was there all the time but did nothing
It did less before.
It did work for me in 2.92. Saved a lot of time.

Awesome - I'm looking forward to this feature. Thanks for sharing
I've been hoping for a feature like this for a while!
ok this is HUGE!!!
Yes! I've been waiting so long for that!
yeah i have noticed that , great feature!
This took my heavy animations frames from 23 seconds to less than 10 seconds. thanks!
Nice!! Finally!!
Thank you Karim, this new feature is awesome
HEY he's BACK !!!
Thank you Karim, thank you Blender 😃
It's a WOW feature
Great feature! Thanks for the so short and straightforward explanation!
This is just amazing!! Really really amazing! This + Cycles X will get things pretty exciting ;)
excellent tip!
Thank you!!
HOLY MOTHER OF RENDERS!! Thank you :).
Nice information, thank you Blender Dialy. :)
Excellent thanks for sharing
thank u for best info...
Beautiful. Thanks a lot
Subscribed 😍😍😍
Wow, that is super cool/helpful.
woov, this is the perfect feature.
Amazing, thanks for sharing this feature.
that amazing
oh nice!
Great... Thank you..
you are great bro.......thanks from sri lanka
Thanks!!! Unfortunately just day before i was rendering animation and scene build time took so many time, but now i will use this feature.
Wow, that's a new one! I use "Fast GI Approximation" and works well too.
Thank you...
we really needed it cause thei fking hate updating shader

@@_bug56 Ok thanks, makes sense. :)
omg yes
For my opinion... This is super useful for rendering Eevee.
I think it's only a Cycles option tho..
@@sourdonkeyjuice yea I just realized it yesterday
@@sourdonkeyjuice but if it’s also for Eevee it’s gonna render SUPER FAST
Thanks!
THanks, would the persistent data cache be affected if a material node is changed? That is would this speed up material tweeking?
Very good! Only one thing... Monition blur doesn't work for me when presistent data is enabled. (blender 3 alpha)
Wish I had known this 3 months ago
Can you help me speed up 2.93 viewport render? It was faster during the 2.8x release but now its noticeably slower.
TANK YOU SOO MUCH!!!!
it doesnt work :( rebuilds everytime when i render my animation. have i forgotten to switch somethin on or of?

It uses VRAM if rendering with GPUs?
So, what changed under the hood? This checkbox was from 2.5+ version. And it worked.
great idea, i wonder if it is used in any other package? Also you still have to render a scene anyway for the first time right?
This is great! the only con that i found is that only works if the character or model dosnt have animation, if it does you will only get the camera animation, but not the character. Unless im missing something, of course. but when i tried it, that happen.

I spotted this badboy Yesterday, I had a large animation scene that was giving me hell with loading times...No more!!!!

RAM usage or Videocard memory?
Hello, for GPU rendering: VRAM | CPU rendering: RAM | Hybrid rendering: VRAM
Great vireo. Will it work with 1060ti card as well?
Will this only be appliable for Cycles?
From the description: "For Eevee and Workbench this option is not available, however these engines
will now always reuse the depsgraph for animation and multiple view layers. This can significantly speed up rendering." I don't know how the depsgraph works but it seems even though it is not available for Eevee it is also getting a speed up.
plz sir tell me this trick will work if i have character animation and any kind of simulation thanks
Will something like this ever come to eevee. Or am I just missing a ton of information about eevee basics
Yeah I saw a big change in my render with 2.93.. the first time I try to render my animation of 250 frames it's crash after making only one image and the second time it's crashed after only render 5 images.. I can not see yet how it's can save me time if I have to look after it for his crashing ;-p
:o !!!!
HOW TO RENDER ANIMATION WITH THIS FEATURE
It looks like this only works on the GPU. My PC has no GPU card and it doesn't work on it
it seems to work when rendering on the CPU when I tried. After clicking on the persistent data checkbox, you must first render once to cache the render data, and on the second render you will see the speed improvement. Or maybe your scene has a fast scene build time so you can't see a difference?

hi, the cached folder goes automatically to Temporary Files, or shall i tweak it to change the folder's destination?
I normally leave the Temporary Files field blank in the Preferences, and explicitly set the TMPDIR environment variable when I launch Blender.
Sorry im a noob. How do i increase memory to make the most out of this? Is memory the same as ram? Or is it how much storage i have? Sorry for dumb question

Omg if this works in my old laptop .
😏 Omg .....
"Increased memory usage" -- system memory or V-RAM (video memory)?
Seems like it uses V-RAM ( devtalk.blender.org/t/persistent-data-limitations/18427/5 ).
yes GPU rendering: VRAM | CPU rendering: RAM | Hybrid rendering: VRAM
This feature should be on by default.
Time is money, so... it's money saver?
Hi! It uses vídeo ram for the caché?
Hello, for GPU rendering: VRAM | CPU rendering: RAM | Hybrid rendering: VRAM
@@karijoart this is sad if it uses a lot of VRAM, most cards only have 8gb which already is super low :( Seems like the 3090 is the way to go if so
I can’t believe...
didn't blender had that feature before?
previeously it supported only persistent images and now it is persistent data
Anyone who tested 2.93 can say is stable for rendering?
Hmmm 🤔
BUGS BUGS BUGS with Persistent Data. loose geometry nodes in render, loose some modifiers.
You could speak a bit faster
You can just increase the playback speed to your liking
