I have been having some shader trouble of late. I have duplicated non-prefab objects in my scene. When I change the texture or shader for one it changes the other copy of the same object. Sometimes a duplicated object will act as it an object by itself the way it is supposed to, othertimes it acts like its a prefab parent who changes all other instances of game objects who share the base model, even though they are not prefab objects. What’s happening? This is the first time I have encountered this and I have been using the same installation of Unity for month’s now.
