      • I have a good amount of shaders/fx files where all have several techniques for various shader level and detail implementations. In a worst case scenario this leads to a lot of similar code being represented in the various vertex and pixel shaders I use, which is really a maintenance hell if left like that. Change code in one place and 5+ other places need the same change. So this leads me to the f

Visual qualities of a material can be described with  shader(s) ! Anyway, if someone could give me some ideas here as
