A procedural rusty metal shader created for Blender. The material features customizable node parameters, allowing users to control both the painted surface and the rust accumulation. Adjustable settings include paint color, metallic amount, specular values, roughness, and paint irregularity strength. The rust effect can be modified through scale, specular, roughness, and mapping controls. The rust color is driven by a ColorRamp, enabling custom color combinations alongside a dedicated rust edge color input.
