This shader node group generates a procedural black-and-white diamond pattern in Blender. The node provides inputs to adjust the scale, thickness, and size of the diamonds. Because it outputs a simple mask, it can be utilized in a variety of ways, such as driving the alpha channel of a Principled BSDF shader to create perforated grids or textured surfaces. It is designed to be driven by the Object output of a Texture Coordinate node.
