- hard—use the face normals. This is equivalent to softenNormals(0).
- conform—same as hard. Computes consistent normals using the connectivity and a heuristic that favors the world's up direction.
- soft—for each vertex, use the average of the adjacent face normals. This is equivalent to softenNormals(180).
- auto—same as soft. Edges where face normals meet at an angle greater than or equal to 30 degrees are shaded as hard edges. This is equivalent to softenNormals(30).
If the conform mode is not successful consider the following options:
The setNormals operation sets the normals of the current shapes' geometry to the desired mode.
