I'm working on a Unity's Project and I want to modify a prefab, more precisely I want to change the texture of a prefab. The problem is that my modification is applied also to other prefabs. I read on the documentation how each of the buttons labeled Select, Revert and Apply works, and what I understood is that the modification should update only the selected prefab.
Here is the Prefabs' Manual which I read.
What am I missing?
PS: I'm not the author of the project, I have to apply some modifications only.
