Coincentric Circle Node Schematic

This basic node schematic will create a starting place for creating and endless variety of forms.

Watch the complete video for details on how it works (I added the color ramp).

Addons are an important Blender component. They provide added functionality to the base program.
Many tutorials will require that you add an addon to Blender. This is a fairly simple procedure.

How to add an addon to Blender.
Edit – Preferences – Addon – search for desired addon.
– uncheck display enabled only if necessary
– after checking new addon, register the new addon (upper right corner)
That is all there is to it in most cases.

If you need to install an addon, follow the instructions for the addon (where todownload from, etc).
