A geometry nodes system for generating procedural roof tiles in Blender. The setup includes controls for grid size, tile tilt, and randomized scale and rotation variations. It features customizable materials with specific parameters for adjusting crack size and color, dust intensity, and multi-color variations. The ambient occlusion settings can be used to simulate moss accumulation. Users can expand the system by adding new tile geometries to the designated collection. The generator is designed to work in conjunction with the Array modifier for layout alignment.
