Step 08 :

Now new Instance or copy (method) dialog box pop up.there is two option Instance or Copy.

  • Instance method : Creates a completely interchangeable clone of the original.
  • Copy method : Creates a completely separate clone from the original. Modifying one has no effect on the other.

choose Instance because we don’t want different material for material override. we modify this material in material editor and it will automatically update ,So choose instance and hit ok.
