Ahh sry im bad at responding here. No they are different systems. Yes Material Layers is what you are looking for. You can create a library of base material layer assets, and then a library of blend assets and mix and match them as you please. To be honest I haven’t seen many people using it. I abandoned it because it ended up being much harder to create reusable blend assets than building something specific. And I found it more difficult to create optimized materials and the material statistics were very buggy. And it was just a pain to manage a whole separate library of materials blends.
