I've been working on this project for 3 months now and I'm nearing the end and doing some touch ups. One of my problems is that my metal texture just doesn't feel like metal. I used a phong to make the texture. The reflectivity of the metal is a big part of the problem I feel as it isn't distorted at all. Could anyone give me some suggestions on how this problem can be fixed? I don't really understand much about refractions but I believe that's in the process of the solution.
