Personally I save all of my renders for winter and use my computer as a furnace to heat my whole house

If you have a blurry Donut after applying depth of field, copy his Aperture settings at 13:52

On the depth of field - the F-stop value makes a difference too - I was still getting an unfocused section towards the part jutting in the camera direction, even after selecting the donut as the focus point. You'll note his value is around 30 (mine was very low for some reason - but good around that 20-30 range.)

Secret render tip:

For large/complex scenes use render layers to use different sample counts for the foreground and background. :)

I'm convinced people who have used blender for as long as Andrew still watch his videos to learn more.

[choenriquez]

I didn't think I'd go through the Donut Tutorial again, but after watching 11 minutes of this, I've made up my mind to start it again! Great stuff, Andrew!

[KnapfordMaster]

For those just starting out, I seriously recommend diving into Eevee and learning how to make it look nice. It's not as good as Cycles but that's not necessarily a bad thing, and once you accept that you can come to really appreciate what benefits it does have to offer. For people like me with a GTX 1050 on a laptop, it's the best option for animation no contest.

Here's a HUGE tip

When rendering, only have blender open.
Even having this tutorial open while rendering is a difference between 20 seconds and ~28 seconds!

[jeremyrobinson]

If the Render Result pops up in a new Window instead of in the image editor, go to preferences > Interface > Editors > Temporary Editors and change the "Render In" field from New Window to Image Editor.

RTX 3070Ti took 11secs/frame on exact your settings. THANK YOU so much for this tutorial! Best teacher!

[Blendergrid]

Great series Andrew!

Bit more about clamping: It's actually not the higher you set it the faster it will render. It doesn't really affect render time much.

Clamping affects the brightness values of the samples that are taken for each pixel.

One nice pink pixel might have samples with brightness values generally around 0.4, 0.6 etc. but sometimes there's an outlier from a direct reflection ray or something that has a crazy value of like 20.

With a low amount of samples, this can greatly increase the total brightness of that single pixel, because the final pixel brightness is determined by averaging over all samples. This can cause fireflies or high amounts of noise.

However, if you use the clamp setting and set it to 10, you clamp off those outlier samples. So instead of a brightness of 20, it's only 10, which reduces the influence it has. The low samples (below 10) are not affected. This trick can reduce fireflies or certain types of noise at the cost of reducing accuracy. (Extreme amounts of clamping, values close to 0, will make all pixels darker)

Happy holidays 😃

What a cliffhanger. We've finally come to a point when the donut is "finished" and eager to render it out then you drop the "But wait! Don't render it out yet, we'll do that in the next part...". Seriously though, thank you for the tutorials.

[ManuelRusch]

The difference between eevee and cycles is pretty much the (lack of) indirect lighting. Adding an Irradiance Volume and baking it brigns the two much closer together.

[FF]

If your donut is still blurry after applying depth of field, make sure your f-stop value underneath is higher

[Marc-WOA]

Impeccable timing, I just built a nice multi gpu system for heavier 3D tasks and I was wondering EXACTLY how to tackle rendering in 3.0. You are so loved by the community my dude.

[CoconutPete]

The most important thing I have learned so far in this tutorial series has nothing to do with Blender, but is more about what to do and what not to do when creating a tutorial... Blender Guru has the art of creating tutorials down perfectly!

[Donnosaurus]

the GPU tip saved me so much time! It was about 50 seconds for a render, now it is under 8 seconds! I am using the Aplle M1 Pro (GPU - 16 cores)

[blenderingD]

if you're rendering on CPU as 50% of blender users are. The one setting to change is tile size, I ran a couple benchmarks on the BMW scene and with all settings tweaked for lossless quality renders I fount that the bigger the tile size the worse it gets, and you also can't go too low. My tile size sweetspot for a Ryzen 3700x 8c/16t was double the threadcount, and I also run the same benchmark on other PC systems and it was the same, you want your tile size to be double your threadcount. Since I found no tutorials on CPU rendering improvements I had to do figure it out myself. So that's my advice for CPU rendering

I Started using Blender a month ago, and here I am back here because consistently it's the best content on Blender I've found. He manages to cover most of the fundamentals all here. So freaking good. Thank you so freaking much brother. I never would have thought I could do this. Thank you for being my first mentor.

[detective]

I have watched all of his begginner tutorials because
first i got banned from using computers when i was in 10th grade
and second time my computer litteraly broke the day after I finished his tutorial and was going to start doing somthing my self.
I am so glad i am finaly doing it
