This is literally the simplest geometry node you can create and it literally does absolutely nothing. Next create a new Geometry Node by clicking the + icon: This will create a new very simple node graph for us, like shown: Pick any Blender Window or create a new one, and change it’s type to Geometry Node by selecting the item shown before (or hitting SHIFT + F3). Now we want to get started creating our Geometry node and that means opening up a Geometry Node Window. With the Blender deities appeased lets start things off by creating a new Monkey Mesh. Start by creating a new Scene and sacrificing the default cube (click the cube and hit X) to the Blender gods. While note the most impressive demo, it is simple and a great starting point. That is to say, it takes the geometry and replaces it with a series of cubes, like this: We are going to create a simple Geometry Node that “voxelizes” whatever you pass in. We will be using the beta version of Blender 3, and do keep in mind, these features are under heavy active development, so if you are reading this from the future, it’s quite possible that some node names have changed.Īlright… let’s get started. So what I am to do in this tutorial is show you about the easiest useful Geometry node example you can create, then we can start expanding upon it, adding new features and functionality. One challenge of Geometry Nodes is, they are somewhat confusing, at least at first glance. So this simple Blender 3 Geometry Node tutorial should be perfect for a beginner. This will enable game developers to quickly create all kinds of projects, from tree generators to entire cities, in just a few clicks and in an easily reusable manner. Geometry Nodes are special as they enable all kinds of procedural workflows without the need to write a single line of code.
With Blender 3 and going into the future, Geometry Nodes are a becoming both more capable and more important. Blender added Geometry nodes back in Blender 2.92 and support has been steadily improving ever since.
