How can I save a node setup, such as procedural texture, so I can easily access it in my default scene. It would be a great help to not have to import or start fresh each time.
That's one use case for Node Groups.
- Select all relevant nodes and group them with Ctrl+G. This way the created group is accessible within all material node trees, located in the Add menu: Shift+A > Groups > Your Group Name
- Save your config as well as the created node group as part of your Startup File under File > Defaults > Save Startup File
