This material node group generates detailed metal surfaces for both Cycles and Eevee render engines. It features bipolar controls that allow users to add or subtract procedural and image-based textures from the material's color, reflection, and bump channels. The shader includes built-in procedural generation for dirt, dust, and edge wear, while also supporting custom image inputs for scratches, weathering, and normal maps. The product includes a set of 32 accompanying image textures. Note that edge wear and ambient occlusion effects are currently only supported in Cycles.
