Corroded Bronze, Verdigris, Steel Rusty, Chrome Rusty, and Iron Cast
I know, I know, Corroded Bronze and Verdigris are the same thing. I couldn't call Corroded Bronze Corroded Gold because everyone knows Gold doesn't corrode. So just imagine that the first one is impossibly corroded gold. These textures require that you have the SPATTER or SPECKLE .SXP procedural textures available. (Yost Group Special effects Disk.) If you Don't have these IPAS textures, you'll have to fake it by making a blobby texture map by hand and replacing the SPATTER and SPECKLE textures in the materials editor.

Chrome Shiney and Aluminum Brushed
These materials require no unusual textures and are just the result of playing around with metallics settings.
