Sets the lighting quality in the current viewport.
0
Faceted. A single color is computed for each face of a surface or 3D solid.
1
Smooth. The colors are computed as a gradient between the vertices of the faces.
2
Smoothest. If the Per-Pixel Lighting setting is turned on in the Manual Performance Tuning dialog box, then the colors are computed for individual pixels. If not, the Smooth setting is used instead.
Note
Existing visual styles are not changed when you enter a new value for this system variable. Any new value entered for this system variable temporarily creates an unsaved new visual style.
