In this video I'm showing you how can you create cartoon roofing tiles. It's procedural so it means you can change it's shape, scale, width and location easily wich is pretty cool I guess.
Around the time when I created this scene, I watched some Erindale tutorials especially one of the Getting started with procedural textures videos, and I'm glad I watched it because he introduced the fraction setting in the vector math node and without this I wouldn't able to make the roofing tiles.
