Hopefully they don't change it again 🤞

i have some learning disabilities and usually rely on self teaching, finding myself getting impatient with videos. however, the fact that you stop to explain what each element does instead of blitzing by is hugely appreciated! thank you very much

I have to say that having spent the last week trying to learn Geometry Nodes - this is far and above one of the best laid out tutorials.
Lots of others tell you what to do step by step but usually fail to explain the what and why of it all - so while you come away with an impressive end result you don't come away with a solid understanding of how to do it on your own.

I really appreciate how you break everything down and explain why certain nodes are needed.

11:05 It's handy to remember that _tau = 2*pi = 360°_ - but if you can't, the *Math* node can convert degrees to radians if you select *To Radians* in the dropdown menu.
In this case, you could just plug it into the _Max_ input of the _Random Value_ node. To speed this up, you can even drag the unconnected input into empty space, and type "radians" into the search box to quickly create a _Math_ node in the right mode.

(It's okay to plug in a grey value into a blue vector here b/c we want the same maximum rotation angle on all axes.
*If you want different rotation ranges for each axis* (e.g. full rotation on Z but only tiny on X & Y), you could use the _Vector Math_ node set to _Scale_ by _tau_ to get 1 to mean "one full rotation by 360°" - or scale by _tau/360_ (just type that into the field and hit Enter) to use degrees.
Or, *if you want to expose this value in the modifiers panel anyway, * you can also drag any _Rotation_ input (e.g. from the _Instance on Points_ node) to the empty slot at the bottom of the _Group Input_ node, then disconnect it again and plug it into the _Random Value_ node's _Max_ input. That way, Blender knows this vector is supposed to be in degrees, displays the values as such, and does all the mathy conversion to radians automatically behind the scenes.)

First video I watched from you and I learned a lot about not just geometry nodes, but nodes in general in Blender! This was an instant "subscribe" moment for me, and I never subscribe randomly, only the really important channels to me. Very good teaching style, I definitely appreciate the "We are gonna use this and this is WHY" approach. It immediately answers the viewer's natural question of "why". I've been watching a bunch of Blender tutorials for how to do certain things, but they always were more like "Do this and do that because I said so", and with that method, it's a lot harder to understand concepts and I end up following directions without understanding why in the world what I'm actually doing. Your style clarified WHY I should put those nodes in that order and HOW I can manipulate them to my liking. You present the logic very clearly to the point that you demystified nodes for someone who has barely any functional knowledge of them. Definitely a very good teacher! Now I can improve my little toy action videos better, thanks!

Doest matter for how long you use blender, you will always learn something handy in those tutorials.

Geometry Nodes and I are not friends, at all. My brain cells are burning up faster than my poor computer everytime I try to understand them...

[DrMerle-gwwj]

There seem to be a great many real Blender experts on YouTube who can do quite a lot of things with Blender. You are certainly one of them. However, you are one of the very few Blender artists whose YouTube videos I have seen who can actually create a good tutorial. This is one of the few really good tutorials I have seen on YouTube. My sincere thanks for providing this video.

[HazySkies]

So glad you're finally doing a tutorial series on this!

Geometry nodes are one of the things I've always been intrigued about, but they just seemed so incredibly complicated, more-so than material nodes, or at least at first glance. But yeah, very eager to see the rest ^-^

[CarlosGomez]

I think GN is the future of Blender. Learning its logic is essential. Luckily, this series of tutorials from Andrew Price is opening our eyes. Many thanks.

[renzesparza]

Very comprehensive intro. Easy enough to follow where i guessed you’d be changing that last module from vector to float

[matthewbrown]

Thanks SO MUCH for working at a pace that allows all of us to follow. Many other Blender Gurus, although super knowledgeable, move so fast that it's difficult keep up with (even using the pause button).

[drewkeith]

Finished 1 and 2, thank you so much for these tutorials, you've single handedly kept me learning blender. I'd love to see more videos covering geometry nodes. Thanks for the amazing content!

If you want to change multiple values all at once, like at 11:47, you click and hold LMB on the first value, then drag it to the last one you want.

[jackcleveland]

Thank you for this tutorial, Andrew. Just when I thought I was really getting a handle on Blender, nodes comes along and upends my world. I've been avoiding the whole nodes thing, resisting learning yet ANOTHER skill set. But now is the time to dive in, and I'm so grateful that awesome people like you are sharing their teaching skill and knowledge. Peace!

Me at 16: “I’ll never use math, let alone geometry, in my life. Imma do something fun instead.”

Me at 31: “Yeah, i’ll just watch this geometry node tutorial at 1am because it looks crazy fun.”

[DragoonySilverwing]

This is fantastic! Was actually reading about geometry nodes lately and wanted to dive deeper into it. Thanks! Your guides/tutorials are a lifesaver for someone wanting to learn 3D. Thank you!

[bottleneckgamer]

Finally Blender guru style geo node tutorials. Love it🔥❤️

[MyBlendr-]

Wow, it will be the first video on Geo nodes I will watch to the end. Honestly, You should do this, I was scared from the beginning of any other :-D

[Suniverse]

man i was searching just that, i followed the donuts tuto for the 3rd time lately and since i kept going on, understanding, rigging, animation, uvs.. testing camera mapping..texture painting and "vertex painting", so i forgot to go deeper in geometry nodes.. so really, thank you for all that
