You can find a bunch of geometry modifiers to play around with in the 'Files' section of this course.
I encourage you to play around with the Geometry Nodes system a lot to familiarize yourself with the environment.

I feel like we need learning objects with this to say whether or not by the end of the course we should know how to do everything that is shown in the video. I am not sure if I should spend a few weeks on this video alone to fully absorb everything or if I should watch it once and move on to the next lesson
For anyone who's confused that they don't have data blocks for the move and rotate geonodes groups, it's because you haven't made those groups/"data blocks" in your file yet.
He has one of them on screen so you can see how it's made (it's just a Transform Geometry node, with translation or rotation set as group inputs).
Great! Very interesting concept! Anxious to start to develop things using Geometry Nodes! Thank you very much!
Thank you that was so nice
Note to other potential new "students":
Seeing this in April 2024. I was expecting a step by step, but really this video is more of a "very general overview" of how Geometry Nodes work. It shows (interesting) things but does not explain how to do them, step by step.
To really get started with Geometry Nodes step by step, better go to the next video: "Example - Rock Generator".
No me sale para poner move en el programa
@Fue mushu Move/Scale/Rotate are not builtin node-groups, for the video I created them as an example. The Transform Geometry node does all of these operations.
I don't get the same options that the tutorial shows. I will find another video online.
yall needa update your videos
@kaydn All the information in these videos is still valid. If you are looking for a video that shows you a step by step guide of achieving something without understanding why this is not it.
I dont get to that "data block picker", and no idea how to find it.
@Kegan Holtzhausen I'm showing where to find it 40 - 60 seconds into the video. Maybe this is a misunderstanding?
At around 1 minute, you click the datablock picker, and have several options, F Move, F Rotate, F Scale and Geometry Nodes. Perhaps this is not what is should be in a clean new project? As I only have "Geometry Nodes"
@Kegan Holtzhausen Ah, I see the confusion now. This list will show you all the nodegroups that you have available in that file.
The ones you see in the video are just simple example nodegroups I created to illustrate that point, but I should probably have explained that in more detail. The nodegroups can be recreated simply with a Transform Geometry node.
In the future with full asset integration it will be more straight forward to attach node libraries and select them directly in any file.
Thanks for this! These tutorials are super useful for the math-challenged among us (looks around nervously hoping there's others here). I should mention that when opening several of the downloaded files in 3.3.1, they're full of "Undefined" errors. Maybe external assets not included in the .blend?
@Nick Jainschigg Ack! I'm more than merely math-challenged. I didn't notice that the blendfiles were opening in an earlier version of Blender. In 3.3.1, they're fine.
@Nick Jainschigg no worries, glad it's working in the end and the videos are of help! :)
Hi, Thank you for this vrey good video but I am getting stuck early in the video. Specifically, what is a data-block picker and how do i activate it. At time frame 1.0 minute into the video you seem to use it to pull down a menu of options in the Add Modifier window that contain such items as Move, rotate (that is to say,, the pull-down under Geometry Nodes only contains Geometry Node without the other pull down options that you show on your video) , ... When I try doing this, these options do not appear. Please comment as what I am doing wrong. Thanks! PS I am using Blender 3.2.1
@steve kacenjar The menu you are describing is the datablock picker. The options that show up in that menu are all the nodegroups that you have in the file. The nodegroups are the datablocks that contain the node-tree and can be shared between files. The nodegroups you see in the video are some simple ones I created to show as an example. In this course I'm not going over how to create and use nodegroups, as that is part of more general Blender workflow.
I recommend you check out some of the example files like this one. You can append the nodegroups there into any file and use them there as a modifier by selecting them in the datablock picker.
Excellent….thanks
Very first step of myself into this node world
Around 6.30 the Move/rotate node u choose from "Group" is gone.... can't find it...any idea why they have removed it?
@Martin Starchel these nodes are a simple example of custom nodegroups. They are not actually nodes in blender but simply created by making a node group using the Transform node and only exposing the translation/rotation/scale input.
Super cool. Looks very handy :)
One chapter in, and I can't stop playing around in Geo Node
Someone left two heads laying around here, please… people are trying to comment here! Very nice intro to geo-nodes, I'm really exited for the next chapters
Wow - you just blew my head off!!!!!
@Jonathan Hudson It probably landed right beside mine!!!
