What's wrong with my node setup and how to do it right? I am using diffuse, normal map, roughness map and height map for displacement modifier. Allso I would like to know how can I hook displacement directly in node setup and I don't know the use of 2 first nodes in my setup (just saw them online always being attached to image texture nodes. So 1)What's wrong with my nodes? 2)How to hook displacement into nodes? 3)Whats the purpose of Texture coordinates and mapping?
Sorry If I am asking basic stuff because I tried searching online but everywhere I find diffrent things with wierd setups full of math nodes and I don't understand witch one to trust more. I am confused so I asked here, If this is possible duplicate please point out Thanx!
