This workflow teaches you to generate unique tileable patterns from Blender's built-in nodes - in this case, a stamped metal pattern. While that may sound exactly like a procedural workflow, parametric represents a level up in terms of flexibility and complexity based on math that generates custom "parameters" for this pattern. Parameterization is also why Substance Designer can do the things it does!
Like procedural workflows, we start from standard Blender nodes to generate a texture pattern. But then we take a deep dive into math operations that you've likely never explored before. These enable us to generate custom tile patterns to suit our needs.
This is a powerful lesson in Blender's nodal shading capabilities. Don't miss it.
