For practice and fun purposes, I created fully procedural C64 by using Substance Designer. It has 4 versions of the product which can be changed by parameters. It's even very close to the one I modeled for days with Solidworks!

It's great to build this kind of hard surface products by procedural image based height and PBR approach. Hope you like it!
