for a current project I used regular planes and applied a solidify and a bevel modifier on each.
Each of the planes should have another logo on it. So the materials all have the same BSDF - in my case a principled shader - but are all different Materials because of the logos. Also there is a material for the back/side channel of the solidify modifier.
Since I used quite many logos I was wondering if there is a way to change e.g. the roughness for all shaders at the same time.
In other words: Is the a way for objects to share the same Shader but all have their own color input?
