Sorry to say, but I was not able to make simple combination with 2 objects (cube,sphere) and three materials (red,green,blue)...
I feel terribly stupid
For me its hard understable whole logic behind all this groups,names,hierarchies etc.
I was expect some extra simple interface. Adding "group_n" like container where I´ll drag objects for mixing. Another "group_n" like container where I drag all materials for mixing. Then adjust some rules and press "combine" and done...
Please, can you create example file for me as I describe above?
(File examples hats/vampires and zombies was not helpful enough for me)
