Use this menu to choose visual quality options and global viewport settings for legacy driver displays.

Shading menu - Legacy
The "legacy" viewport drivers are Direct3D and OpenGL. These drivers have specific configuration options in addition to those on the Viewport Configuration dialog.
Interface

- [shading styles]
-
Choose from among commonly-used shading styles as shown in the Rendering Method panel of the Viewport Configuration dialog.
- Display Selected
- Shows a submenu with options on how to display selected geometry in shaded viewports. For more information, see below.
- Lighting and Shadows
-
Shows a submenu with options for lighting and shadow previews in viewports. For more information, see below.
- Transparency
-
Sets the quality of transparency display in the viewport:
- None No transparency display.
- Simple Less accurate transparency display; however, viewport redraw is considerably faster with Simple.
- Best Highest quality transparency display; longer redraw time.
Note: The Transparency setting affects only viewport display, and does not affect renderings.
- Other Visual Styles

- Smooth Displays smoothing, but doesn’t show highlights.
- Facets + Highlights Displays highlights, but doesn’t show smoothing.
- Facets Shades faces, but doesn’t display smoothing or highlights.

Display Selected submenu
These options affect how selected geometry appears in shaded viewports.
- Shade Selected Faces
- When on, selected faces display in a red semitransparent state. This makes it easier to see selected faces in shaded viewports.
When off, selected faces are indicated by red edges only.
Lighting and Shadows submenu
Viewport lighting affects viewports only: It has no effect on how the scene is rendered.

- Illuminate with Scene Lights
-
When chosen, the viewport uses lighting from light objects in the scene.
- Illuminate with Default Lights
-
(The default.) When chosen, the viewport uses lighting from the default lights.
Ctrl+L toggles between using scene lights and default lights.
- Scene Lights Control (Nitrous viewports only)
- Displays a submenu for managing lights in the scene:
- Auto Display Selected Lights When on, light from selected lights is automatically displayed in shaded viewports. Default=off.
- Lock Selected Lights Locks the selected lights.
- Unlock Selected Lights Unlocks the selected lights.
To "lock" a light means that the light will stay on until it is unlocked, whether or not the light casts shadows. When a light is locked, choosing Auto Display Selected Lights does not turn it off.
- Enable Hardware Shading
-
When enabled, the viewport is displayed using your system’s hardware shader.
Keyboard shortcut: Shift+F3
- Enable Shadows
-
When enabled, previews shadows in the viewport.
- Enable Ambient Occlusion

- Configure
-
Opens the Lighting and Shadows panel of the Viewport Configuration dialog, allowing you to turn hardware shading on or off and change other options.
