Normal edit modifier creates jagged edges I installed blender 2.77 (latest update) and used a model created in 2.75. In the face mesh I used two modifiers, subsurf and beneath that a normal edit modifier to have control over the sahdow on the face. In some weird way it is producing jagged edges on the jaw area (where the normal edit modifier has effect). Auto smooth in the object data is on. 


Anyone has an idea what is causing this?
The problem has been solved. In the latest build an extra option has been added to the normal edit modifier. It is a field called "Max angle". Standard it gives a volume of 180 degrees. As explained by the developer, if you bring this value below 90 degrees (say 30) it prevents the normals from inverting and producing the jagged edges. Thanks for this life saver Bastien.
