I made a pack of common metals you would see in real life. I think this metal material is the best looking one because of the true displacement.

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

A: This material has true displacement which means that the geometry (Geometry means anything that is a face, edge, or vertices.) on the mesh (A mesh is what makes the shape of the diamond plated metal ball look like a diamond plated metal ball.) is changed, while regular displacement just uses shading effects to make it look like it has bumps but it doesn't actually have bumps.

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.
