Now this is all fine for creating a one-color shader - you don't have to deal with any of the "physics" of light and know how to set these up - it's done.

But - now combining with pattern generators is a little tricky. It's not clear to me how I could modularize all the possible procedural patterns of other plugins, such as the "Spots" plugin that was derived from a post of mine long ago. How would we combine BBGlossy and Spots? Or BBCandyPaint (a substance) with BBStripe (a pattern) ?

Snarly - what are your thoughts on EZMat having the ability to smash together several plugins. (One for color, one for substance, one for surface deviation (bump or disp), etc.)

And then - for situations where one or more of these is not homogeneous, but rather needs to be modulated - what then?

And - for situations where a shader is itself a composition of other shaders, such as a checkerboard tile that wants to combine three plugins (tile1 tile2 and mortar) ????

All of these kinds of things are very easy to do with matmatic. But the presentation of the stacked and nested plurality of plugins??? Obviously this is what node-based UI is for, but this whole thing is about avoiding that altogether so it is EZ. So what is the solution?
