I have a scene with two mountains, one is blue, and I would like the other one the small one) to be pink.
In edit mode, objects have been separated (P).
When I click on the second object and add a new material with the "+" sign of the material tab, it creates a new material.
Then I SHIFT + RMB the materials, to be able to "Copy Material to Others"
I then go in the new instance of the material (by clicking on the small mountain), and change the color with a green (I know I said pink... forgive me)...
... and all the colors change! But I was just in another color, I just wanted the small mountain to change.
Even the other instances of materials I created with the "
+" button have all changed to green suddenly. Every one of them. On both meshes.
So, are node-based materials like physics simulations, in that "there can be only one"?
Obviously it's possible to recreate materials from scratch every time, but... there's gotta be a way to "unlink" these material settings, so that I can make a new object, apply this material and then change the color or texture, based on the existing tree?
Here is another example of trying to duplicate a material and all the materials changing together when I only edit one of them:
