Video

This tutorial helped me so much. I was struggling making a basketball before this video 🙏💯

For me, the M3 Max Floats between a laptop 4060 and 4070, and that is good enough. That fact that can be had on something pulling 100 Watts of Power and with over 18 hours of battery life is just amazing. Nvidia cards are awesome. The 4080 Laptop is just amazing. But Windows breaks anytime you try and push it. I got tired of fixing windows instead of working.

I’m still gonna buy a rtx laptop for 3ds max but this is very useful. Thanks!

great analysis!

So good. keep it up!

This is very helpful, thank you!

Very helpful. Thanks for sharing.

Thanks for sharing. I am putting together a new project that uses SVG to 3D.

I really wanted to subscribe, the editing and content is really good but this god awful ai voice is unbearable.

I don't recommend using denoise for animations, especially when using volumes in scenes as clouds or mist.

I find it super helpful to increase the minimum number of samples particularly in scenes that have an overall darker color scheme, and lots of shadow. I had an indoor scene where my max samples were only about 128 (for animation), but because the minimum samples were set to 0, Blender kept undersampling the darkest areas, leading to some really weird denoising. You can set your noise threshold actually fairly high if you up the minimum samples, because then even darkened areas still get enough samples that the denoiser doesn't have to guess too much on them, leading to a smoother color gradient, instead of weirdly mushy shadow interiors.

Showing denoise difference with CZcams's quality is not a great idea, mate.

So does this mean it's now better to render each frame as a whole frame. Because back in the day you were supposed to break it up into smaller chnunks. But it seems like adaptive sampling would be less effective with that technique

ADJUST NOISE THRESHOLD NOT only resolution and Sample Count.

04:30 I could be wrong but I think if the min_samples is set to zero this is how it is setting the min_samples: const int min_samples = (int)ceilf(16.0f / powf(adaptive_sampling.threshold, 0.3f)); adaptive_sampling.min_samples = max(4, min_samples); so unless you set the threshold to zero the min sample number shouldn't change based on the max sample count. but then the adaptive_sampling itself is doing some quirky bitwise operations (that I don't want to think about now 😊). at first glance I assume that probably changes the stopping conditions so that it will process more samples which from the user's pov feels like a higher min_samples. -idk xD

I just render in the lowest sample rate with "good enough" noise, apply denoiser and use a scene grease pencil to keep the sharpness. I am just lazy so I use render artifacts as my style. It made my job a hundred times easier that I may return to CZcams at some point idk.

me watching this in a high end laptop (I dont need it)

But one problem thou, i personally usue sample limit at just 128, and if it gets blurry due to denoise i tend to just render the scene at a higher resolution like 4k or even 8k, it tends to clean just as good as havingn the base 4069 base sample count that blender uses but is way faster

I rarely use Cycles as I've noticed quite a few creators, keep recommending cycles, like Pixxo 3D, his videos are great, his graphics card is always compatible and he always when making textures goes with the highest possible textures he can do, with the latest versions of Blender , just Cycles doesn't work to well with me. Ryan King is a good one, as he will use both Eevee and Cycles, and shows different ways to get textures to work in a similar way to Cycles, and ways to make sure your computer doesn't struggle with rendering.

That’s not a Boeing 747! 😡

I need to Try and Error until i see what works best for a particular project

when using denoise oftentimes you'd want to disable adaptive sampling outright, as non uniform samples will confuse the denoiser and make it effectively hallucinate detail and create strange artifacts

They even renamesd Samples to Max Samples to make it clear it's not the same setting as pre 3.0 Cycles. And yet the "reduce samples" mantra has not changed on Reddit, it's the ancient "wisdom" that just won't die.

I am a little less confused now. Thank you

I have Blender 4.1.0 and I had 5 of them available in the preference. The other 5 were missing unless we have to download them? Those 5 addons that were missing are: Easy HDRI, UV Squares, Blender Kit, ImagePaste and FSpy. Thank you very much for this video. Looking forward to seeing more of your good advices.

Through a lot of testing I found that noise threshold very often produces inferior results than just an equivalent render time without it - and that's especially true in scenes that are inherently very noisy across the entire image (like volumetric heavy scenes). That being said noise threshold is incredibly useful if there are parts of the scene that require a lot of samples and other parts that require barely any at all (for example a sky, hdri or just transparency). It's possible that this is because I never touched the minimum sample value and perhaps Blender is setting it too high as you said in the video - knowing that information now I will be trying to set the minimum samples manually to something very low like 32 and see if that helps. Still it's weird when I have a scene with a noise threshold set to some value and then the renderer proceeds to leave some areas pretty noisy and then spends more time on areas that are already clean. It feels like it's working pretty much backwards, but again, that might just be me.

0:28 You should have said holy grain

This is a really well thought out and informed vid. May you have many many views! Thanks for sharing and taking the time to put this together so well. Your efforts to make it understandable have truly paid off, I can promise you.

3:20 time is the same

Based on my underestandings , noise threshold is the aspect ration between Signal and noise , for example a value of ( 1 ) noise threshold means the aspect ration between signal and noise would be 50% , 50% , so if u decrease the noise threshold , you will increase the aspect ration of the signal compared to the noise , so u get higher quality image

thank u boss

What a coincidence, just two days ago I watched your sampling video and was waiting for the promised noise threshold. Thank you!

thanks, very helpful

Very helpful information thank you !!!

Can you please drop a tutorial on texture projection mapping and texture painting? In blender 4.0

I had a problem in UV part .. the part of the UV ai scaled and rotated, shitf the procedural ball texture and I follow step by step :/ Idk how to fixed :(

It's the best video to speed up Cycles render 🎉 you explained it very clearly ❤, Thanks for your Research

This is very helpful, also you sound like Stavros Halkias.

I always appreciate things to know like this. Like relearning the basics? Anyway I don't care how long it takes me to learn Blender, I just want to learn. Thank you very much.

The voice sounds off to me, it’s a bit hard to focus on what you typed

You can simplify the first step by just simply going to the object add single vert menu. And then extrude from there.

Thankyouu😔

Bro I am having 8gb Ram 64 bit and an SSD and I want to build basic hard surfacing models can I go with my current configuration do I need to increase more,

Did you make this example scene? If so, where did you find the textures?

How to render in little block like that?

For realistic scenes I honestly prefer the noise you get with lower samples. It's like built in film grain in a way

Why would you compare denoised low sample image with denoised high sample image? I mean you don’t need denoising on 2000 sample image (in this particular case). You just f* up your render with denoising bro

You forgot to talk about Noise Threshold and Ray Depth ( new in Cycles X ). I think for still images very high samples ( 4K+ ) and low noise threshold ( 0.0075 - 0.015 ) and denoiser off/on depending how important material details are is top priority because it will render in a such way that noise is even on the whole image. For animations low sample count ( 64 - 512 ) should be priority and high threshold ( 0.02 - 0.3 ) w/ denoiser on, lower ray depth and ideally using static noise if Cycles has this feature.

Much ram do we need for blender ?

Seems a bit low for any scenes with fine detail prone to artefacts. I lean toward 4k at 1024 samples. 0.1 noise threshold for fast stills. No noise threshold for quality stills and animations (overnight render for the latter).
