I have to display several versions of the same object, with only the color changing. My first approach was to duplicate the mesh and add a different material to each.
My problem is: when I want to modify the mesh, I have to do it on each object separately. I tried to have different objects with the same mesh, but the color seems to be linked to the mesh and not to the object.
Is there a way (even programmatically) to have the same mesh in different objects with different colors?
I'm using Cycles and my material is a node material in which there is only one changing color.
