I made a pack of common metal materials you would see in real life. Since I can't put more then one image in a post this is but one of the metal materials I've made.

Q: What makes this metal material different from the rest?

A: This metal material looks like it's been brushed, this is a common industrialized technique where you sand processed metal sideways to make a neat pattern on it, none of the other metal materials I made have this pattern which makes it unique.

Q: What properties does this metal material have?

A: The properties that this metal material has is that it is metallic, and it has edge tint.

Q: What is edge tint?

A: Edge tint is where you look at a metal object and the edge of it is a lighter colour then the rest of it, to see the effect more clearly look at a metal object and face forwards toward it.
