I’ve always wondered if there is a way to combine two materials ontop of each other without fully copying one materials node setup into the other one and than using a mix shader node.
Ideally like this. You have an object, say a laquered piece of wood and you want to add another material for surface defects on top. Anything like raindrops, scratches or the like.
Say you have a material already perfectly defining your wood, and for the sake of it, say it is a complicated node setup.
Say you already have a material already perfectly defining your defects, and for the sake of it, say it is a complicated node setup too.
Now normally I would take the wood texture and copy paste the nodes of the surface defects into it and use a mix shader to combine them. Essentially this creates a new material combining the two.
What I am looking for is a fast and simple way to keep the two node trees apart (and the individual materials intact) and simply kind of drop the semi transparent surface defect shader onto the base material. Similar to what you would do in a photo editing software. Base material and drop a surface defect layer on top.
How do you do this without combining the two node trees & copying nodes in between them. Is there an add-on which can achieve this?
Thanks for your thoughts,
