Hello, thanks for your answer — that’s exactly what I was looking for!
However, I’m working in version 5.4, and the node “Set Material Info” has a structure pin that I don’t know how to handle.
I tried creating a custom structure myself, but it doesn’t connect to the input. I also can’t split the pin, and the only result I get when searching for “Make” is the node in the picture: “Make ComponentMaterialInfo” — but I can’t do anything with it either. 
Which version did you find that node in?
