Grungit is a Blender add-on that automatically generates wear and tear effects for 3D models. It applies procedural weathering, edge wear, dirt, and scratches with a single click while preserving your existing material node trees.

The tool features multi-object support, automatic unwrap packing by material, and includes an advanced mode for granular control over weathering effects like clearcoat and dirt layers. It integrates edge wear generation that respects normal maps and includes an integrated 1-click PBR baking system. The generated effects are topology-independent, animatable, and fully compatible with EEVEE and Cycles.
