2. Find the Prefab in the Asset Manager

  1. Navigate to View -> Asset Manager

  2. Enable the "Allow Editing" option.

  3. Search for your prefab by name. Careful name here means name on disk, i.e. Content Browser, the name in the Scene Hierarchy Panel may not necessarily be the same.

  4. Copy the Prefab's Handle.

3. Modifying the root Prefab's ID.
