Procedural Patterns is a collection of node groups designed for generating procedural mask patterns within Blender's Shader Editor. The package provides a foundation for custom material creation, featuring specific tools like an animated rain shader, Voronoi family pattern nodes, tiled hexagons, and brick layouts. It also includes a Scatter Node designed for randomized vector mapping to add variation to surface textures. The package comes configured for Blender's Asset Browser, allowing users to drag and drop the node groups directly into their projects. It includes several demonstration materials and volumetric setups, marked with fake-user tags, to illustrate how the core node groups can be applied in practical shading workflows.
