Beginner Blender 4.0 Tutorial - Part 6: Geometry Nodes

In this video you'll get an introduction to geometry nodes by scattering points, which are then instanced as round sprinkles.

80% knowledge about Blender
20% knowledge about how donuts are made and why they look the way they look

I have been working on this project for a month now. Restarted the actual donut 6 times. Restarted the icing 3 times. Restarted the sprinkles 4 times. Finally just finished part 6! If youre reading this dont give up! You will finish the donut! One step at a time. Thank you Blender Guru!!!!

16:48 was a bit unclear, but our Guru selected the "Group Input" node, then hit "N" on the keyboard, and double clicked on the "Density Max" label to change it's name.

After I finish this donut and render it, I'm going to buy a dozen donuts to celebrate

I never saw someone successfully monetize only one object for years in 3D as much as you. Amazing :D

Anyone struggling with slow zoom and panning after shrinking the Donut, it's a pretty easy fix.
Go to Edit --> Preferences --> Navigation, then under auto check Depth. This should make your actions scale properly to your zoom and make navigation feel the same as with the bigger donut.

I love how he remade this series so many times. And everytime it gets better.

If anyone else has the issues that your sphere sprinkles are huge, hit CTRL+A on the UV Sphere to apply scale

*Note: If your icing part's missing the top vertices when you try Weight Paint, remember to unhide them by 'Alt+H'

GEOMETRY NODES - at 7:41 I actually had to attach the "Object Info" scale output to the "Instance on Points" scale input for this to work properly. Otherwise, I got HUGE spheres all over my donut. My first thought was to click "relative" in the "Object Info" node and that fixed the scaling issue but all of the sprinkle spheres were offset in a bad position.

[gragalakaisel]

If your sprinkles look SO SO SO SO much smaller, after applying scale, make sure to also apply scale on the icing, you might have only applied it on the donut.

[SELS]

Folks, if you're having issues with your icing "exploding" after the apply scale at 20:25, go back to your Solidify modifier on the icing and reduce its thickness value. I chose 0.0003m for my approx 0.125m (X/Y dimensions) donut.

This lesson is very easy to follow. Easier than the last version for sure.

One of my biggest criticisms though with these tutorials is that Andrew's 20 years of experience has him on a different level than us and I think he forgets that sometimes. He tends to fly through some steps without mentioning what he does. He's pretty good about it like 98 percent of the time but that ONE thing that he forgets to mention, takes him two seconds, because he knows how to do it, but for those who don't know how to do it, they have to spend an hour to hours figuring out a small step that could have been mentioned. I can understand that his time is limited but so is ours sometimes.

In this case, it's when he renamed Density Max to Sprinkle Density. He just hit N without mentioning it and didn't tell us that
that was what we have to do to rename that value. If you would have simply mentioned that we had to hit N, we could have seamlessly gone to the next step. (To rename Density Max, hit N to pull up the properties menu and you can rename it there).

Thankfully I figured it out within a couple of minutes thanks to having to deal with stuff like this before, but unfortunately many beginners who are relying on him to teach us articulately will be spending an hour to hours googling how to rename that value. Mentioning every step is kind of critical and I've had to spend hours in the past trying to figure out things that could have been mentioned in one second.

This isn't just Andrew either. It's many of these guys teaching Blender. EVERY DETAIL MATTERS and one small mistake can ruin your project just as they have ruined several of mine in the past.

If you happen to be following this tutorial, and you're at about 5:30, and you're wondering why the ball doesn't appear for you the same way it does for him, as well as why the menu is different... It's because your mouse cursor need to be in the viewport segment, NOT in the geometry nodes segment. I didn't even realize it could matter, but had to rewatch a couple times to figure it out

[DoctorFruitbat]

19:38 If the scaling doesn't seem to be working, press N to bring up the menu on the right of the screen, go to Tool > Options > Transform and untick everything next to Affect Only.

I feel so excited every morning to wake up to a new episode and continue to edit my yesterday’s donut where I left off. Also feels like we’re part of future history by watching these one by one as they get released 😂❤

[Inish]

I have never touched 3D software before and the same little old me has currently a donut with sprinkles on top.. just awesome! 🤩👍 Can't wait to learn more, thank you so much Andrew!

[jimle]

I really liked the analogy of the bugs hitting the large and matchbox cars. It helps to visualize what is happening. Thanx.

[sophiasoh]

Thank you for the great tutorial! I used the exactly same geometry nodes to generate Christmas ornaments on digital trees and was really happy about the result!😊

Is it just me or is he like a superhero to 3D? Thank you for saving us from the complex world of blender.
