[SHELVED] Material Layering Feedback for 4.19

[Chosker]

so it sounds like hassle-free upgrade to Layered Materials

I see potential for the system only only in two directions. First being fresh projects made from scratch, where all the planning was done with the system in mind.
Second being a usage case where all asset texturing is done exclusively in the engine, potentially involving baking blended mat attributes into textures.

either of your 2 directions drive me to the same conclusion I had before with Layered Materials: I can’t think of it as something for production due to the shader complexity derived from it
