"In this third Fundamentals tutorial, we will look in-depth into how to generate a variety of Voronoi cell patterns. We'll learn how to utilize these patterns with several essential nodes, including the powerful Flood Fill node. Understanding how to create these patterns is extremely useful when building organic materials. Combined with the Flood Fill node, you will learn how to build natural shapes efficiently. We'll also learn how to create utility nodes to speed up your workflow. By the end of this tutorial, you will be able to build natural looking rock formations."
