Shader tutorial: Old Copper

Tutorial for a corroded copper material, with downloadable shader and test model (The tutorial uses Happy Buddha, but the version on BlenSswap has one I sculpted myself)

I take a quick look at the scene setup for a product-type render, then dive into my process of making a shader like this.

That’s all for now, I hope this material can be useful to someone!
