How do I create metal materials in Cycles? I'm trying to make a gun for an alien space ship and I need to know how to create a dark gray metal look. I have tried mixing a Diffuse and Glossy BSDF, but it isn't quite what I am looking for. I need some light falloff to help get that "extra touch", but I don't know how to do that.
I would recommend applying a normal map, using a glossy shader and then bumping up the roughness to your liking.

Example




Here's what I did

Glossy shader color (hex)

616161


Roughness amount

0.05
