Hi neishy, no need to copy the Node Frame, but I’d try to use the Output of one of those Multiply Nodes (of those Cracks) and plug it into the Factor of the Mix Shader, You might need a Colorramp or Map Range Node in between, to control the values.
You can of course try your idea and see what happens. It’s always good to experiment a bit, but if that doesn’t give you the resul;t you want, try my suggestion.
