Geometry Nodes 3.0 Tutorials by Crossmind Studio

If you are new to nodes and want to dive into Geometry Nodes, you might want to start with the Geometry Nodes 3.0 Tutorials by Crossmind Studio on YouTube. The tutorial series consists of 6 videos, each around 15 minutes. While the first video covers the tutorial series itself, the rest is to familiarize beginners with nodes. So let’s start with the second video.

 02 Whys and Hows – Geometry Nodes For Beginners / Blender 3.0

In this video, Ram explains the benefits of procedural modeling. Instead of starting from scratch every time, we can also adapt existing models. As an example, he shows a spline that defines the location and shape of a river. Now, if you need a river in another project, you adjust the spline and some attributes. Compare this with older workflows where we build everything from scratch.

03 Interface and Basics -Geometry Nodes For Beginners / Blender 3.0

In this third video, Ram talks about downloading Blender 3.0 (alpha) and Interface Basics. We start with the default cube and transform it. Interesting is that we can animate all the settings in the nodes. And because this animation is part of a modifier, we can easily assign the same animation to another object. By adjusting the animation in one modifier, we can update the animation in multiple objects simultaneously. So the animation is recorded in the modifier rather than the object.

Another handy tip is to use Alt when dragging a node out of its connection. You will keep the node but also the connection in the tree. But better watch this video because visuals tell more than I can explain here.

04 Applying Materials -Geometry Nodes For Beginners / Blender 3.0

Because Geometry Nodes is a modifier, we can’t assign materials within Edit Mode. Instead, we need to assign materials in the Geometry Nodes Editor. In this video, Ram shows how you can assign different materials to different parts.

05. Understanding Basic Math

If you are not into math, you still will understand basic math like addition and multiplication. However, surprisingly addition and multiplication might work out differently than you think in applications like Blender. For example, many values in Blender are between 0 and 1. So if you multiply 0.5 with 0.5, you get 0.25. What I mean by that is that multiplication doesn’t always mean more. Often, addition is used as an offset and multiplication to scale.

Ram also explains numbers like integers, floating numbers, and vectors. And he goes further by describing how you can make an animation of two meshes going the opposite direction. The thing is that he is using one number with some math after that. This concept is fascinating, so I suggest you watch this video and practice yourself. Oh yes, and you will learn how to animate the hands of a clock.

06 Displacing Geometry

This video is essential because you will want to displace mesh quite often. Displacement is a fundamental concept of Geometry Nodes, and I see other tutors using it frequently. The node you are looking for is Set Position, and I suggest you get the hang of it as soon as you can. From here we also start with Vector Math.

Enjoy the Geometry Nodes 3.0 Tutorials by Crossmind Studio. After this I recommend the tutorials by Erindale.
