I have a model of a person in my project and I found another .obj file online. I imported it into the project and changed the name of that to the name of the original object. I also changed the name of the new material to the name of the old material. Then I deleted the original file and the object does not show up on the scene anymore. Any help would be **greatly** appreciated! P.s. I am using unity version 5.3.4.
