Smart Weathering is an add-on that applies procedural wear and tear effects directly to existing materials in Blender. It allows users to introduce dirt, edge scratches, fingerprints, smudges, wetness, and dust without the need for UV mapping or texture baking.

The tool operates through a single node group managed by custom interface utilities. These add-on features let users quickly append the weathering effects to base shaders, copy and paste configurations between materials, and preview specific effect masks. The procedural system automatically adapts to the object's shape, size, and cavities.
