It as been a very long time since Nobiax release a new free package. This new pack include 36 metal plates (1 diffuse + metalness for 36 normal maps). The diffuse is not copper, you choose the type of metal (copper, gold or whatever) in the color of the material in Unity5, UE4 or whatever engine you use. It goes from basic shape plates, to slightly sci-fi, to Victorian style 😀

You can found all info and comment at his deviantArt page and then download from there. Or you can also download the new metal plates textures pack from my GoogleDrive 🙂
