Procedural 3D Modeling Using Geometry Nodes in Blender

Constructing a Procedural LED Panel

In the previous chapter, you learned how to create a procedural spiderweb by making use of convex hulls.

In this chapter, you’ll learn how to create a procedural LED panel by using named attributes. We will need these named attributes to save attributes inside of our Blender project so that we can link various Blender workspaces together.

We will start off this chapter by explaining what named attributes are.

But before that, these are the topics we will cover in this chapter:

• What are named attributes?
• How do LED panels work?
• Creating a node tree
• Adding group inputs to the node tree

What are named attributes?

Named attributes can be thought of as variables inside your Blender project.

Attributes can ...
