Use these options to set what happens when you select Mesh Display > Reverse.
- Reverse normals on
-
Specifies what elements have their normals reversed.
- Selected faces
-
Maya reverses the normals on the selected faces. This is the default setting.
- Selected faces, then extract
-
Maya reverses the normals on the selected faces and then extracts, or splits the vertices.
Note: The Reverse option can result in non-manifold geometry, where polygons that share an edge have reversed normals. Some tools cannot work with non-manifold geometry. See Clean up, simplify, or validate meshes.To avoid creating non-manifold geometry, use the Select faces, then extract option. This option splits vertices so as not to create non-manifold geometry.
- All faces in the shell
-
Maya reverses the normals on all (selected or unselected) faces in the shell.
- User Normals
-
Specifies whether or not user-defined normals are affected by the Reverse operation.
- Preserve user normals direction
-
Specifies that User-defined normals are not reversed when using the Reverse feature. The default setting is off.
- Reverse user normals
-
Specifies that user-defined normals are reversed when using the Reverse feature. This is the default setting.
