Create face normals

Select whether to unlock or lock face normals.

Unlock vertex face normals

The edges surrounding the vertex face are hardened if it is possible to do so, and the normals unlocked. This is the default setting.

Match face normal

When Match face normal is set, the vertex/face normal value is matched and locked to its current face normal.
