Possible to simple render high quality shiny metal texture without Vray/Brazil/FR?

Yea MLK that is amazing.

I need some tutorials that will help me learn about GI and Protons and Radiosity and HDRI and whatnot. The only thing I know is Global Illumination which is I’m guess environment light?

I don’t even know what they do in the first place. So anything on what they are might help :).
