VizPak: Worn is a library of over 50 material shaders designed to add realistic surface imperfections to 3D models. The collection focuses on common materials like metal, plastic, and wood, incorporating subtle signs of wear such as micro-scratches, dirt, and smudges. These materials break up uniform reflections and add non-uniform details to replicate lived-in, real-world surfaces. The library is integrated with Blender's Asset Browser, allowing materials to be dragged and dropped directly onto objects, where users can adjust the scale and strength of the underlying texture maps to fit specific scenes.
