Indeed the RenderMaterials table is the one you want.

Just 19 hours ago I posted a snippet where you can see how I loop over all materials:

Issue Programmatically Saving "Raytraced" (Cycles) Renderings

Here a script that does a capture using the ViewCapture script. Use this method if you don’t want to use the dashed command version. # Material switcher # and Raytraced viewcapturing import scriptcontext as sc import Rhino.Render as rr import Rhino as r import Rhino.DocObjects as rdob import System av = sc.doc.Views.ActiveView cycles = sc.doc.Views.ActiveView.RealtimeDisplayMode oldpasses = cycles.MaxPasses cycles.MaxPasses = 2 def capture_viewport(name): cycles.Paused = True view_captur…

In this specific script I pick with some extra conditions, but the simplest form to create a list with all materials is:

import scriptcontext as sc
rmats = [rm for rm in sc.doc.RenderMaterials]
