Material Functions are reusable sets of nodes used within a material graph to simplify complex operations, improve workflow efficiency, and ensure modularity.
This allow for a lot of flexibility and time savings as they can be applied to different materials without needing to recreate the same nodes over and over again.
You know it’s time to consolidate nodes into a function when you start wrapping them in comments (to identify their purpose) and when you find yourself repeating steps.
