This is a personal project for me to practice HardOps, MESHmachine and DECALmachine (Blender Add-ons). The purpose of this exercise is to find a balance between where I need to use geo and how much I can get away with just decals. Creating decals using DECALmachine is a breeze and the parallax shader makes them very convincing.
If you are interested in the decals, I just released the pack and model in the marketplace:
