Hello, I liked the way to damage edges so much that I had to buy Wireframe pro. I had not thought of using it in this way before. If Eric is improving Wireframe pro to make a dirty up shader, then I need it to do 2 functiions: collect dirt in corners and create nicks in edges. I have model of a casting that I am trying to find away to dirty up as the product shots I create look a little too clean. The file is created in a CAD package the brought into CarraraPro. Because the boxes are boring military green I'm trying to make them look more interesting and real. Aluminium underneath with paint on top. This is my first attempt and will be playing with it alot more. Look forward to the upgrade, Thanks, Andrew.
