Add Character Control and Animation to our Hero/Heroine - Unity 3 Game Development - page 138

The extra bone meshes are usually exported from other 3D software,
depending on the arist or animator who sets it up. Someimes, we
can use these meshes for collision detecion for the atack acion, if
we have a ighing animaion atached on the character.
We don't need to show the mesh here, so we can remove or hide it, but we will
remove it because we don't have to use the Mesh Renderer component in this case.
7. Let's do this by clicking on the Heroine_animate in the Hierarchy view.
8. Then, we will use the search box in the Hierarchy view to search and put bone in
this box, as we can see in the following screenshot:
9. Let's click on the first bone back_plate_bone to bring up its inspector and go to
the Inspector view, then right click on the Mesh Renderer component, and click
Remove Component to remove it as we can see in the following screenshot:
This will bring up the Losing Prefab popup; we just click Continue buton to break it.
