Reverse Normals Options

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.
