What are named attributes?
Named attributes can be thought of as variables inside your Blender project. They can store data for you in the form of the different datatypes, including but not limited to Float, Integer, Vector, Color, and Boolean.
As these variables are project-wide, we can use them to link various workspaces together.
A lot of things are controlled using attributes – for example, the Geometry Node editor, the Material node editor, and some entries in the Physics simulator in Blender. In this exercise, we will be using them to link the Geometry Node editor and the Material node editor.
The node that we’ll be using to store these named attributes is called the Store Named Attribute node.
The Store Named Attribute node will store the result of a value on Geometry in an attribute name. The geometry on which this information is stored depends on the Geometry input socket.. In Figure 12.1, you’ll see the Store Named Attribute node:
