Worn Edges is a tool that makes it easy to create a worn look for your props.
It completely creates the worn look to your liking, and bakes it all in a texture, no painting or editing required. (So no hassle with painting over UV-seams)

It can be used for worn metal, paint, wood, concrete, rust, dirt, ...
