How to copy objects in unity3d?

Question

Unity

How to copy objects in unity3d not as an instance of a prefab (changed it, all instances have changed), but copy an object and this will already be an independent new prefab. I need several prefab trees (created using the standard tree tool), which I just didn’t do, but all the trees on the scene are changed as one

Answer 1

Select copy and menu GameObject -> Break prefab instance
