Wood & Metal Fence - Procedural Material Exercise

This is my first productive attempt exploring Material Maker (by RodZill4), it's magnificent. Looking at its GitHub repository, I'm a bit amazed that it's entirely written in GDScript. I thought most people who would use Godot to build programs would use other language bindings, such as C++ or Rust.

I had a bit of experience with Substance Designer in the past, but don't have access to Substance software any more. Then I've been using Blender's node shader more often, and it also feels quite comfortable. So now Material Maker feels quite familiar, and I managed to produce this two material in several hours (in 2 days calendar).

I have plans to do with these two materials, but I'm still working on the 3D model.
