I made a node group that contains a color ramp, and in order to control the color ramp from the outside I read that I have to use drivers. I have never used drivers before and feel lost right now.
So I copied the data paths from my color ramp sliders into the color ramp. The problem is that in the driver editor, I need to assign a material.
But I want to be able to use the node group in different materials.
The last picture shows two objects with different materials. The material of Suzanne is assigned in the driver editor and works the way I want. But when I change the sliders of Suzanne, I also affect the purple sphere; if I'm in the sphere's material, the sliders do nothing.
Is there a way to make the drivers work without assigning a material? Or can I make a variable that always links to the current material?
