You can use even less vram, essentially, by using Render layers so it renders each layer one after the other then combine them in compositing.

@GurnoorMarjara 10 месяцев назад

Even for animations?

@MrTomyCJ 8 месяцев назад

@@GurnoorMarjara yes, you can save each frame as an exr multilayer (or use file output to save each layer to its own image) and then combine them in the compositor. I'm not sure if this saves VRAM though. To save VRAM you can also trt rendering in smaller tiles. It can be slower to render though.

@spiderjerusalem8505 6 месяцев назад

For renders - yeah, but sometimes you don't even have enough VRAM to use viewport. This is super useful for GPUs with less than 20 GB VRAM.

another two options in the render shelf to minimize RAM usage (with the price of longer rendering time): * Disable "Use Curves BVH" * Enable "Use Compact BVH"

@andreasklindt7144 2 года назад

Thank you very much! I somehow missed it that Blender can show in the status bar how much memory it's using. But if all the optimization inside Blender is not enough and Blender keeps on crashing because you don't have enough memory, there is another possibility to increase the virtual memory that is actually offered by your operating system. Good old fashioned memory swap files.

@SchemingGoldberg Год назад

VRAM is your GPU, swap files are only for RAM (which is for your CPU), so swap files don't increase your VRAM. If you have an integrated GPU, then the VRAM and RAM are shared, so a swap file would work. But for dedicated GPUs (like AMD or NVidia) then it won't work.

@fetusness 2 года назад

Thank you Ryuu!! Didn’t know about this and I looove cycles

@nickcrofts1659 Год назад

I had success in the past when needing to keep my textures hi res but blender was saying it was it of vram when rendering (with viewport in wireframe) by going to performance in the render tab and changing my tile size to something lower than the standard 2k. It might work for others as well

@nickcrofts1659 Год назад

I also had success changing texture size for parts of the material that don't need to be high for the model I'm using, such as leaving normal, height and base at 8k and dropping roughness and Metallness down to 2k but that won't leave good results for all models, it would depend on the model.

@PonteRyuurui Год назад

@pedroschereibermunhoz750 Год назад

You can also render using the command prompt without opening blender at all (UI)

@TruthSurge Год назад

wow, no wonder BLender crashes all the time. I have in my scene one plane (4 vertices) and one stretched torus with 289 faces and the default light and camera. That's it. ANd already 2 GIGABYTES of VRAM is used. ! for WHAT? 2 BILLION chunks of data that could hold an alphabetic letter each is used? for one plane and one primitive mesh torus. :( I don't see what all it needs to load up into VRAM just from even add-ons and stuff. That stuff should be sitting inside regular RAM. I have both CPU and VRAM enabled for render. Maybe it will try to use both. I don't know. Thanks again for these tips.

@cashtonbriggs2135 2 года назад

Im still trying to wrap my head around 24GB of video😮😮...but the purge feature will come in really handy. Thanks Ryuu 👍

@BenleGentil Год назад

Tesselation alone can get you there quite quickly (:

@KuroSanArts 2 года назад

That option in simplify looks handy! I'm guessing it just does a temporary resize of the textures used rather then me having to spend an hour in Photoshop batch resizing? lol

@PonteRyuurui 2 года назад

pretty much

@ajaysupahiya3299 Год назад

Bro you can batch automate the resize of texture in photoshop. This way you have more control incase you dont want to resize some important textures.

@ArfatXeon Год назад

@@ajaysupahiya3299 you could also batch convert them to lower quality jpegs, problem is that changing file extensions unlinks the textures

@ten-ub4xd 7 месяцев назад

what about baking? im stuck on a project because my file is so heavy, the VRAM is constantly on the vurge of reaching its max and quiting. ive lowered the geo alot, also i used substance painter to make all the textures. most are at 4k. Im modeling a shoe. ill try this simplfy trick , just curious if baking would make a difference? Many thanks enjoyed your vids!

@GisleAune 2 года назад

What is the purpose of manually resizing (or using an addon to automate it) when the simplify panel can cap texture res? Is there a noticeable speedup in the loading step?

@PonteRyuurui 2 года назад

what if you wanna drop one specific texture

hi the 1st method always reverts back to original resolution no matter how many times i try dropping file size low. Help

@TruthSurge Год назад

Thanks for this vid, Hans Zimmer! hahahah I'm sorry! You need to do some fake Hans Zimmer interviews. Bashing all your soundtracks! hahahah "leak" that onto the Internet and watch the drama! hehehhe Man... Why is it a crash if Blender uses up all the VRAM? Shouldn't the graphics card or the CPU understand when a call to VRAM is made and it wants to STORE 1000 but only has 100, the CPU tells graphics card to unload a chunk of VRAM to HD, etc, just like any OS does when RAM gets full? Anyway, I have 64 G of regular RAM and 12 G VRAM (4070 TI card) so I guess for crashing you can use CPU for pre-renders up to the final, then switch to VRAM plus CPU? I don't know. I just started trying Blender about a week ago really. I'm just learning.

@DaaronIrwing Год назад

@ProjectLifeDev 2 года назад

in short there is no magic tool to save VRAM ^^ the only thing you can do is to keep in ur scene all the necessary stuff and ofc if vram not enough downscale ur textures :) i remeber i was trying to render a scene with 3 males and 3 females animation plus the room (eevee render) whenever i clicked render animation ..it was yeah right try again so i started downscale textures and then i could render the thing .ps i run with 16 ram and 8gb gpu ram . also something important ! stuff i could render in 2.83 version i couldnt render in other versions ..weird huh thats why even tho i have all blender versions i still use 2.83 FTW anyways downscale textures is legit but even that at some point if u render big scenes you might need more ram ,lastly some scenes that cant be render in cycles woth gpu compute they can be rendered with using cpu (if u have 1 year time to render ofc ) not that cycles with gpu is fast thats why i personaly cheat using eevee i love watching rendering frames in 30 seconds heheh instead hours heheh (i mean imagine rendering a niamtion with 4k frames on cycles ..... so for me that i dont go for photorealism eevee is the winnder :)

Hell, pass on the optimizations I'd just love to figure out how to make Blender use my entire VRAM at all. I have a 3090, Blender caps out at about 10.3GB of VRAM before spewing "Out of memory" or crashing.

@franciscomanuel7377 Год назад

Hi Sir, I would love that you answer me. For blender, AMD or Nvidia? I'm a complete beginner in Blender, I could test your course. And my old GPU is died. So my brother is gifting me RTX 3060 12 GB or RX 6650 xt with 8 GB Vram. So, I worry if it's critical Vram or nvidia or AMD. Specially I would like to learn modeling in 3D. Actually I'm mostly 2D artist and computer technician.

@PonteRyuurui Год назад

nvidia is more optimised for Blender for sure. Go with max vram possible.

@franciscomanuel7377 Год назад

@@PonteRyuurui Okay, thank you very much. 🙏

@furynotes 2 года назад

If have a 8gb limit for vram. With most GPU's. That is barely manageable.

@PonteRyuurui 2 года назад

well you ll need to work on smaller textures then

@stuffmcstuff399 Год назад

You don't need more than 4k textures for things, truth be told - Unless you want a highly detailed hdri background. You also have render layers which splits it all up and you can combine all the parts which makes it more manageable for graphics cards with lower vram.
