Realistic materials

[Sylynn]

I just yesterday upgraded my copy Architectural to 2020 and love the new "Physically Based" rendering technique. What I'm looking for are tips as to how to get the most out of my materials to get the best possible render. I understand I will be a bit limited compared to a more "pro" product such as CA Interiors, but I think I can do better. Metals seem to be fairly good right out the gate, but wood and fabrics I'm having difficulty getting texture out of it. I'm used to working with bump maps in many other rendering tools, but it appears to lack that functionality. 

 

Any tips or guidance to some would be greatly appreciated!
