Creating a prefab instance

You can create a prefab instance by dropping a prefab file into the scene, dragging it from the Files view or the Blocks view.

When the active editor is a Scene Editor, the Blocks view shows the Asset Pack file items and the prefab files:

Also, in the Prefab Instance properties section of the Inspector view, you can click in the prefab name to open the prefab file.
