The ColorMix node applies metallic hues, while the cubemap's imperfections create a polished effect. By connecting the Normal input of the Reflect node to a seamless Normal map, the material mimics the intricacies of real copper. Just like mastering the thrilling challenges of Moto X3M, understanding these materials requires precision and creativity.
