Material
Encapsulate a set of shader graph nodes into a single module.
Overview
Material nodes help you divide your graph into subsets of nodes, each with distinct inputs and outputs. A Node Graph appears as a single node within your main graph. Editing that node hides the main graph and gives you an empty space that you fill with additional nodes. Use that space to build a specific portion of your main graph, and use the Node Graph to define the inputs and outputs to that separate space.
