How could we have missed this for so long?
We don't need material Phenomena to use shader lists. We can use a regular color Phenomenon. Just list multiple shaders for the root.
root = "shader1"
= "shader2"
= "shader3"
We found this in our preparation for the Phenomena training class. Check out page 87 (3rd edition of the 1st volume in the Handbook series), Rendering with mental ray. It is used in the Phenomena named "textured_mtl_sh" at the bottom of the page, and is described in the second bullet point at the top of the next page.
Why is this great? Because hardly any of the 3D applications provide an interface for shader lists, and it is the easiest way to add a custom bump shader to a material, in a color Phenomenon, for example.
root = "mybump1"
= "myillum1"
Or put a bunch of geometry shader objects into one geometry Phenomenon:
root = "mygeo1"
= "mygeo2"
