Procedural Materials - Skill Development Project

As a part of Upskill in my 3rd year at University, I had to choose an area that I had less knowledge about, so I chose to look into Substance Designer, and how to produce custom materials. This led to the production of four unique materials that should be able to work cohesively if used within the same environment, perhaps with a blend of structures & nature. The aim was to ideal have these materials available for future use, as they should be able to be changed into a new variation if need be.
