This pack contains 100 metal stencil textures designed to add surface imperfections to 3D materials. The textures are provided in both JPEG and PNG formats at mixed resolutions. They can be utilized as roughness maps, height maps, or displacement alphas to generate the appearance of metal cracks, edge wear, and general surface degradation. As standard image files, they are compatible with any 3D modeling, texturing, or sculpting application that supports alpha masks and texture inputs.
