Materials help

Hi, I wonder how people learn how to use materials. I understand the basics of materials. But I want to get into more advanced stuff. But I just don’t understand how people do these things…

The unreal engine documentation gives quite a lot of information about materials:

Use these as guidelines to get to know the material creation process (and its advanced features).

If you realy want to improve there is no other way then testing these features yourself and design your own materials and try to make them look as good and as real as possible.
