Creating node groups
Single nodes (shaders, textures, input, or whatever) can be grouped together, and this is probably one of the best ways to organize our workflow.
Thanks to node groups, it's easy to store complex materials in ready-to-use libraries. It's possible to share or reuse them in other files, and they can also be used to build handy shader interfaces for easier tweaking of material properties.
Getting ready
Start Blender and open the 9931OS_02_interface.blend file.

- Now box-select (place the mouse cursor in the Node Editor window, press B, and click and drag a box to include the nodes you want to select) the Diffuse BSDF and the Glossy BSDF nodes, as shown in this screenshot:
