Just one detail about decreasing the tile size: It helps you to render big scenes when you don't have much VRAM available. With a powerful GPU it's generally unnecessary make it smaller but when you can't render in 2048 tile size, decreasing it would allow you to render in exchange of more time actually. This is my experience messing around with it xD

You missed something while talking about denoising. Under advanced settings in Cycles sampling panel there's animate seed option. That one needs to be disabled in order to avoid flickering between the frames. In fact, quite important. Also, I haven't seen anyone mention this but since 3.6 version, maybe even one or two versions earlier not sure, there's Turbotools add-on inside the Blender. That's accualy separate denoiser. If used properly can give even better results that Optix or OpenImageDenoiser.

A note about adaptive sampling: It's worth trying out a scene with a lower sample count and lower adaptive sampling value in complex scenes, as it seems that the AI/algorithms were set up for images with uniform sample counts. In my experience the varying sample counts from this can cause artifacts in the denoiser. To prevent issues try increasing the min samples near to a quarter of the total samples and messing around with values as always. I usually use a value between 0.01 and 0.05. The second image at 14:50 looks like it uses a smaller sample count or some other setting on top of disabling caustics, but it's also possible that the reduced noise from the lack of caustics is causing the adaptive sampling to give it less samples and therefore increase the artifacts in those areas. On top of disabling the animate seed option that someone mentioned to reduce flickering, using the automatic scrambling distance option can also help reduce noise in renders by allowing nearby pixels to have more similar random values. Setting the multiplier to 0 is also a great way to visualize converging times and figure out what is a good sample count for you! Transmission bounces are required for any transmissive materials, that includes glass that uses transmission, refraction, etc. Transparency bounces are only used for materials with alpha (i.e simulate a transparent material with no internal bouncing and only a surface) or using a transparent BDSF.

Some tips for faster renders. This is coming from someone who renders stuff at work on an ancient PC with no GPU only an or 9th gen i7 CPU. 1. High resolution (~3000x3000) + low sample size (~32) + Noise Threshold 1. This is really good for low end PCs. 2. Small tile sizes (~128 for me) are good for CPU rendering, while larger ones a better for GPU rendering. 3. Sometimes adding textures after in Photoshop is actually faster. If you have a large wall with a lot of bump-mapping.... just do it in post. I can pump out simple scenes under 5 mins, more complex stuff under 10-15 mins.

Good to see Noise Threshold being properly explained. So many people still just parrot "lower your samples" when this has not been the primary control for render quality since 3.0. They even renamed it from Samples to Max Samples to show it's defintiely a different setting, but no the parrots just started saying "lower max samples". Lower max samples does one thing - reduce the samples available to the noisiest part of your image. Exactly what you don't want to be doing.

About using your CPU in addition to the GPU for rendering: It depends. Usually, it *should* be faster, but there also are a lot of cases/scenes where it actually slows down the rendering, in comparison to a GPU only render. Always test which is faster before rendering your animation

Intel i5-10400 + ARC A770 16GB Render time : GPU + CPU = 8m02s GPU Only = 6m29s note : since it's taking too long to render at 4000samples I reduced to 2048 samples and noise threshold to 0.03 So clearly if you're CPU is slow it will actually hinder the performance.

Dont know if anyone said it before, but if you use a bigger format, like 4k instead of 1080 and use 1/4 of the samples the denoiser is able to mantain a lot more details and sharpness. You divide the samples by 4 because 4k is 4 times the area of 1080p. Max Hay uses this technique and downscales the render to 1080p afterwards. You don't actally have to change the resolution since changing the format % to 200% should be the same thing. Hope it helps someone! P.s. Please do a full video about temporal denoising techniques and fireflies/artifact removal :P Loved the video from Southernshot, but I was asking myself if there are any other workarounds (maybe even in AfterEffects or premiere)

If youre using GPU, deactivate Tiling, Turn on Denoiser Optix or OpenImageDenoiser, low the samples to 12 and in output in resolution activate 200% With this you will denoise a bigger image that will have more details and you will get a better result with the denoiser because this one understand better the image. And deactivating the tiling, its because GPU handle better the whole image than tiling images. Doing test the tiling always got more time than the whole image.

I’ve seen a few people recommend that low samples high resolution trick and I’m a bit skeptical about it. At least in the scene I’m testing that has volumetrics, the results are quite a bit worse and has very noticeable blotchy denoising artefacts in dark areas. Not to mention the slightly slower render times even at such low sample counts and you’d be using exponentially more storage space if you keep the renders at that 200% scale. Doesn’t seem worth it to me.

AFAIK, Tile size optimizations only works if you have more GPU cores than what cycles can use with parallel processing in a single tile. If you have equal to or less, then you are best off rendering 1 large tile. If you have more, your better off rendering a number of tiles that has the largest number of cores per tile simultaneously without going over. at least, that's how I understood it. I don't know how many cores cycles is optimized for. if it's 4 cores, and you're doing CPU rendering with a threadripper with like 60+ cores, multiple small tiles will be faster because it's rendering multiple tiles at a time, but AFAIK the average consumer-grade GPU can only render a single tile at a time, and reducing tile size and increasing the number of tiles, actually increases render time, rather than reduce it, because it's only 1 tile at a time, and switching tiles takes time to load new data to the GPU. I am NOT a programmer, or really any kind of expert, I just watch a lot of youtube videos, and tried to render on my laptop and this is what my experience of it points to. simultanious tiles = total # of cores MOD max cores per render.

Another tip: render from the command line. Some utilities online can do this, for those unfamiliar with shell scripting (like the Flamenco add-on, which I use), but this is another way of managing memory. This way, you don't have the full Blender UI running in the background while rendering - helpful for longer animations. A middle ground to this is to lock the Blender interface while rendering (meaning you can't use the UI while it's rendering) by going to the top menu -> Render -> Lock Interface.

why not use optix for still images? it uses the rtx card, not the cpu. so it is faster and let me multitask when i am rendering. by not taking my cpu as hostage. unless, open image is lighter on my rtx and let the card render faster bt splitting the load to the gpu and cpu. what do you think ?

Hello, I see that you are well versed in Blender, I would like to ask you a question. What settings would you recommend for rendering fur? I have a character model with millions of hair particles and even in a simple scene where only this model, it renders badly, dirty. I have a good computer, 3090 RTX graphics card.

@KaizenTutorials 2 ай бұрын

I think in this case you're best off to render things in separate layers like I show in the end. This way you can render with separate samples and noise thresholds. Now you can take everything that's not fur and render it lower quality with denoising and the fur on high quality, but since each render focusses on it's own thing it's going to look a lot cleaner!

Hi, thank you for a extensive video on one of the big alltime problems :) Thy for the work you put into this great video.. dont take my rambling to serious if you read this ;) a bit of nitpicking on things where you are a bit unclear in what you say: Optix: I absolutely agree that on most reasonable systems for most scenes CPU+GPU is probably faster. But rendering with GPU+CPU is not always faster. It only will be when your CPU can handle preparing the render overhead while also rendering. On a weak CPU fast GPU system this can increase GPU idel time, while it waits for new data... It will not only depend on the System but also on the data that has to be prepaired. So its also sceen dependent. For samples you are talking about an image with one "color" .. needs only one sample. I would say unlit objects souch as emission shaders. The color has nothing to do with it. Denoisers: "since optix uses an ai powerd alogrithm using the RT cores on your GPU it has a way more stable result for animation renders" Sorry - this makes no sense. Optix and Open Image Denoise are both "AI powered" and saying that the RT cores calculate better then a CPU would be like saying numbers spit out from a calculator are better then numbers from paper. I totaly agree with your advice though :) but pleas dont make up reasons. Persistand Data ... this one im not shure how it works. But for shure it dosnt just prepaires data once beforehand and then renders on... then animations wouldnt work. Judging by the bugs it has led to in the past i would guess that it trys to update data only when nessesary. Best

@KaizenTutorials 2 ай бұрын

Thanks for your input and kind words! As for your remarks; I agree GPU + CPU is a discussion that will depend on a lot of points. Both the scene and the hardware are points to note for if this will work or not. However from what I've seen from people telling me in the comments, most people with OK hardware do seem to get a boost from using both. This might also be because a lot of more recent CPU's have integrated graphics. I get what you mean with the unlit objects. However the goal of a sample is to determine the color of a pixel, or atleast that's how documentation on path tracing seems to describe it. Therefore I think colors have something to do with it, although if every pixel would have a solid, unlit color, but unique at the same time, 1 sample would still be enough. So you're absolutely right on that! As for the denoisers; this is what I gathered from research. I'm honestly not sure how they work, but Optix does infact use RT cores on RTX GPU's, which is why you can't use Optix on non RTX GPU's. This unique feature could be faster. My analogy would not be calculator to paper, but simple calculator to a fancy one with additional computing power. Persistent Data is a weird thing. Obviously it doesn't store everything, since it would indeed not work in animations. And in my previous video on this subject I recommended people NOT use it on animations, since it created artifacts with moving objects. However this doesn't seem to be the case anymore. I think the data it stores does not include relevant data for animation anymore or something?! Hard to find proper documentation on these things sadly.

I havent tested this in blender but the smaller tile sizes apparently speed up render time in rhinoceros (cad software) when using cycles rendering on the CPU. They claim that the more cores you have, the smaller you can set the number such as 16, 32, 64 or 128. Smaller numbers for more cores. While GPU rendering, you generally set it as high as you need for the scene. I tested the GPU & CPU rendering (optix in your scene) and I got worse results just as always compared to GPU only. I dont know what you did differently but I am using a 4090 with a 7950x3d and also 64gb of ram :I

@DiverseGreen-Anon 3 ай бұрын

I just tested roughly with the tiling set to 2048, 64 and 16 and the tiling is not parallel anymore and appears to be only for memory constraint situations now. The overhead of copying the tiles and files in and out of memory makes it slower the smaller the tiles (higher amount of tiles needing to be stitched) and the random values for the noise and denoise appear to be changed as well, resulting in slightly different lighting on first glance and across multiple frames (more flicker). I used 64 samples in cycles on the CPU to not have to test these for 20 min each xD (on 2048 samples)

@KaizenTutorials 2 ай бұрын

It's weird how the same hardware can behave differently. My renders usually vary in time too, even if I render the same frame multiple times, the times always vary. All my tests with tiling did nothing, but then again I didn't test using CPU only, since I'd never render using only CPu anyways haha Thanks for sharing your tests/insights!

@DiverseGreen-Anon 2 ай бұрын

@@KaizenTutorials Rendering with CPU only really is good for testing new materials as the compiling of the shader for cycles rendering is (supposedly) almost instantaneous while it has to compile these for cuda/optix first when you switch to rendered view/rendering with the GPU if it isnt already cached. Another benefit is the area of cloud/server rendering and you want lots of "vram" to render a big scene. Here the CPU rendering can be the way to go as well, as it is often much cheaper to rent a server with a good CPU and lots of system memory (which is used in place of vram when using CPU) than it is to find a server with a cheap GPU that also has tons of vram. I heard that (design) studios often use CPU rendering to dial in the look and switch to GPU rendering later for the animations, if they have enough VRAM.

I haven't downloaded your scene so I don't know how you have setup your glass material, but as a general rule I would not recommend to set the Transmission bounces to 0. Because if you have not setup some "fake" glass material where you mix in a Transparent BSDF or other Alpha transparency, but either use only a Glass BSDF or Principled BSDF, glass is a transmissive material and will need Transmission bounces or otherwise everything seen through it will be black. By the way, the channel to make a glass material in the Principled BSDF is therefore called "Transmission", not "Transparency" 😉 The Transparent bounces (which are by the way not dependent on the Total bounces unlike the others above it) are used for Alpha transparency which is produced by the Transparent BSDF or the Alpha channel in the Principled BSDF and also controlled by the density of volumetric materials.

@@KaizenTutorials As I said, I have not downloaded your scene so I do not know how you have set it up. Is there anything to see behind the glass except for the world environment? Are the windows single sided planes or do they have a real thickness for correct refraction? The thing is, transmission bounces at 0 work for a single-sided glass material if there is no object behind it (otherwise the object would be black). If your glass has a real thickness, it will no longer be transparent, because the rearward face will be black through the front. If you have a single face and nothing to look at behind the window you're good, because the environment will be visible no matter if you have 0 bounces or not. So as I said, works for you but I would not suggest this as a general rule.
