[Create] Photorealsitic material

Good day,

I’m looking for a good understandable tutorial for Photorealisitc Materials. There are many samples like the Realistic rendering demo, but for me I do not find any good understandable Tutorial where you learn how to create very good materials.

Gives me New Ideas how I can set up my worldsettings and so on but not as I want.

It might sound like that I want to have EXTREMLY SUPER HARDCORE TEXTURES 4D etc.

No I just want to learn what I have to do to get materials like in the Realistic Rendering demo

Yours faithfully
