Quality of Materials Imported from 3D max, tutorial.

Is there a tutorial out there so as to make my materials used in unity look as realistic as possible? I have no problem importing them from 3D max but sometimes they don't look very realistic. Thanx

Look for baking tutorials. Understand what Bump Maps and Normal Maps do in Unity using their shaders. Lighting is very important as well. Try books by Jeremy Bren.. http://www.amazon.com/Digital-Lighting-Rendering-Jeremy-Birn/dp/0321316312

or this website for a quick tutorial http://www.3drender.com/light/3point.html
