NormalSmoothing

This shader shows you the normals on your mesh so you can see the result of normal smoothing more explicitly.

An icosahedron with normal smoothing set to 35 degrees:

The same object with normal smoothing set to 40 degrees:

The same object with normal smoothing set to 45 degrees:
