man get yourself gpu.... i know many can not afford a gpu, but rtx 3070 for 450 dollars makes blistering renders without affecting your cpu, so you can do whatever you want while redering. The gpu can do BMW benchmark in seconds, and makes video render times almost instant with editors that support NvEnc. if you decide to pick a gpu, as a computer amateur/builder i can recommend to go Nvidia if your main usage is rendering and creating. AMD makes the most sense to gamers in terms of power and price. Best regards and happy holidays, quality content btw.

1: when using volumes to lay smoke/fog over your scene dont use world-volume, instead put it in a cube which only covers the area you actually render. 2: before every render i save the project, close blender and restart it just to push F12.. sometimes it reduces the rendertime by 30% mostly when i use projects which use a lot of memory in the viewport. 3: when i started blender my pc crashed a lot while loading up the lights and preparing the render. i found out for myself that if i press F12 to start the render and then minimize both windows as fast as i can until its starting with the tiles (taskbar turns green). after that its safe and sound. not sure if the last two are just me but i am on a 8gb ram/1gb vram pc..

[@wailfulcrab]

Depending what volumetric it is, you can also use Eevee to render the volume fast then combine it as render layer in the compositor. For example clouds.

You can also render in the windows terminal. It's the most stable method. kzbin.info/www/bejne/pWqsiGxse86mpLc

I've shared this with more than a few people but in my case, the test render I had was 38 seconds before all this and then down to 17 seconds.

256px tiles for nVidia graphic cards were the recommendation under Blender 2.7. Since 2.8 Cycles works different. After several test renderings I could cut the rendertime nearly by half while reducing the tile size from 256/256px to 64/64px. But I use CPU and GPU for rendering. In my case also the Auto Tile Size Plugin didn't work properly. In a test render with recommended tile size the render time was 20% higher.

[@DECODEDVFX]

Wow, thank you!

[@soundkoala3748]

Note that there was recently (i think in 2.82) a huge optimization for rendering on the GPU with lower tile sizes to make Hybrid rendering (CPU + GPU) more viable. So that's a different story now and the old principle that larger tiles are better for GPU is not accurate anymore. I found that in complex scenes, 64x64 or 32x32 mostly works the best on my Ryzen 5 1600 & Geforce 1080. Also I'm kind of missing the Light Paths and branched path tracing options in this video.

Another nice one is to run Blender on Linux. The file grab system is much more efficient, that really matters on the initial scene set up rather than the GPU tile render. So this will depend on what you're rendering but the time savings can typically be >30% compared to Windows.

If i'm not mistaken, if gpu is limited to vram it can borrow ram you have. From the previous version of blender there was a patch that ram can be used if vram is limited. The gpu can borrow ram so make sure you have around 32-64gb of ram. I have a 16gb ram and my gpu has 6gb vram it crashed when it got too many objects to render due to vram limitation and it says "out of device and host memory" GPU out of device due to vram limitation and host memory the current ram which is 16gb. I added more ram on my computer it's now 32gb and I was able to render the scene.

[@DavidAllen_0]

Blender 2.82.7 Render Times: BMW scene: 1 minute, 8.33 seconds Classroom: 7 minutes, 14.18 seconds And I downloaded the newest version, here are the results: Blender 2.90.3 Render Times: BMW scene: 1 minute, 3.34 seconds Classroom: 4 minutes, 53.31 seconds However, this is with my laptop's Turboboost turned OFF (it'll reach 100C within seconds with it on, so I had to use ThrottleStop to disable it). That's the downside of having a laptop. Desktops have better cooling, upgradable hardware and cheaper in terms of cost vs performance. I also undervolted my GPU, CPU and Cache by 110mv. This improved my render speeds by about 5% from the tests I did last month when I started using Blender. Also I've never known about the Auto Tile Size addon, I already love it :) Thanks!

[@TheMartinScott]

Most laptops are designed with cooling that can keep the CPU below the 100c thermal throttle limit. If a laptop is hitting 100c, look into replacing the thermal paste on the CPU. Go with a non-conductive, thick setting paste, like IC Diamond. Laptops flex and run hotter than desktops, which is why the thermal is not as effective as when it shipped from the factory. OEMs also tend to use mid range 'grease' instead of a harder high end paste, and with the flexing of laptops, there often develops as much as a .5mm gap between the cooler and the CPU, which is why a thicker paste works better. (This also applies to the GPU.) I'm sure you have seen a bunch of people mention this if you are using ThrottleStop, but I wanted to mention this here for others reading through as well. Also a bit of anecdotal information, the worst laptop my techs have encountered that was running 100c all the time, is now running at 70-80c under full load at 4ghz. (9750h)

I dunno, I'm using Blender 2.93 and the built-in denoiser creates fantastic looking renders without any visible artifacts that I can see, and I'm only using 128 to 256 samples for rendering. You also don't have to enable it for EACH render, just turn it on with a single click when you start your scene and your good to go for however many times you render. Setting up a denoising node is a hassle and I don't see any difference in final render quality.

Omg tysm im doing roblox GFX and roblox GFX intro commissions, and someones animation was taking SOOO long to render! this helped.

if you are doing animations you might want to stick with eevee rendering. its not as realistic as cycles but eevee renders in almost real time

[@theCreativeSav]

The Tile size advice doesn't work for my computer! My gpu renders best in 64px. I don't know why

[@mikerusby]

The one thing I have noticed re denoising is that if you use a low number of samples and expect denoiser to make it suddenly look good, then its not going to happen. What seems to happen is that is removes noise , but the samples are not high enough to make it look good overall. ( leaves lots of artefacts) The more samples i use the , the better the image looks after denoising. i guess it depends hugely on what you are rendering, but I do VR stuff, so having it look spot in is important to me. Takes me 9 minutes to render my street scene in VR, at a 1024 samples and image size at 4096x2048. its not for animation at the moment so that's ok I have done indoor VR scenes where i have used a lot less samples and it looks fine, so guess its heavily dependent on a lot of things, lighting , image size etc

The best thing I've found about tile sizes is to make sure the tiles divide evenly into your resolution (I usually use 120 x 120 which is a little faster than 240 x 270 for 1920 x 1080 w/1080 ti) so it's not rendering small slivers on the edges. Auto tile size gives me like 16 x 16 which in 2.83 is faster and works good for most scenes with a lot of small light sources, but with hdri or sun lamp bigger tiles work better for me.

[@Dutch3DMaster]

I have been on 2.83.7 for a long time since the versions after it gave me problems during baking (weird Z-depth errors that I found no way to solve, along with 2.93 being sensitive to crashing a lot). I rendered something out in 2.83.7 that took about 3 hours for one frame (it had a fog effect in it and lot's of lights, so that didn't help). On 3.1.2 however, with all the improvements made to Cycles, at the same amount of samples the rendertime for one frame was just 30 minutes! (Along with using a tile size of 2048, which due to my old idea's of how big that was in the older Blender versions was not suitable, but was actually the fastest setting, anything lower and higher proved to be slightly slower).

Oh, I also have overclocked the 2700X to 4.1GHz with the stock cooler. It boosts the performance by 6-7%. So you should probably take overclocking into account. And from some other tech videos, I have found out that RAM speed also impacts Blender rendering performance quite a lot, 10-15%. If you have a Ryzen CPU your RAM speed should be 3200 - 3600MHz C16. But for anyone looking to upgrade their GPU I would advice on waiting a few months for the nVidia 3000 series as it will drastically improve Ray Tracing performance, about 4-5 times better. That's what I'm doing right now saving my money for that. Cheers

The denoiser is very good, but it isn't magic. If your render is really noisy it will start to look smudged after denoising. The cleaner you can make your final render, the better - even with denoising enabled.

Thanks. You didn't mention the settings for adaptive sampling. Are you just using the default values? What do those settings do?

[@DECODEDVFX]

0 is default. It's the setting I almost always use. The top number is a noise threshold. Basically it tells cycles when the image is clean enough to move on. Typically you want to use a number between 0.1 to 0.001(smaller numbers are less noisy but slower). The second number sets a minimum sample count per pixel. The default setting uses the square root of the total sample count.

Idk how that worked, but it originally took about 30-45 minutes to render a single frame and now it takes about 40-50 seconds. Thank you

[@DECODEDVFX]

Awesome.

Gosh I thought this was a video about how to make wine quicker because of the thumbnail, it was too realistic

[@adityahegade5202]

03:55 Hey, new Blender does not bake the denoiser data into the image... I think I saw a seperate output added to the Render Layer node whenever I turn on the Denoiser.... But I have never used it, so can't be too sure...

wow i wish i can afford a budget computer with medium hardwares, although i still use an old celeron cpu with only 4gbs but this tutorial actually helped me a lot

[@siham7010]

Thank you so much brother for this amazing video. I wanted to ask why AMD 2700 and not Intel? I do Characters and use hair particles, large textures and Sculpting. What do you suggest about cpu choice? Should I focus on more cores(AMD) or powerful cores(Intel). Thanks again.

[@DECODEDVFX]

AMD Ryzen CPUs offer much better price-to-performance compared to Intel right now. I use lots of heavily multi-threaded applications (including Blender) so AMD made the most sense for me. Intel chips do offer some advantages for Blender (such as simulations) but most of the things you do in Blender will probably be faster on an AMD chip (especially rendering).

@@DECODEDVFX Thank you so much for replying Sir. I wish you the best.

Hate updating blender? Run it on linux and package managers will make update process quick and easy. (Using linux improves also performance of blender - it should be noted in the video as it is actually one of ways to improve cycles render time.) Another thing regarding nodes: good script node could replace many other nodes and is faster.

if you use a gpu change the tiles size to 512x512 it’s crazy how much time sit cuts off

[@CamSpaghett]

Unfortunately for me I have to render with cpu. When lowering my tile size it’s actually considerably slower which I found weird

[@DECODEDVFX]

If you're using 3.o or later, you can safely ignore the section about tile sizes. It's irrelevant now.

How do you render a animation using the composting instead of default

[@miaf111]

I’ve made an animation that’s 43 seconds and on the timeline when you record it, it’s ends at 1040 BUT I’ve been trying to render it, and it is so slowwww. I use blender 2.78, but why is it so slow. I think it is going to take weeks :(

Thanks! This was super helpful!
