Undo View Change / Redo View Change
Undo View Change cancels the last change made to the current viewport. Redo View Change cancels the last Undo in the current viewport.
Save Active View
Save Active View stores the active view to an internal buffer. If you have framed a shot in any view other than a camera, use Save Active View to preserve the viewport’s appearance. The saved active view is saved with the scene file. Once saved, you can retrieve it using Restore Active View.
Show Transform Gizmo
Show Transform Gizmo toggles the display of the Transform gizmo axis tripod for all viewports when objects are selected and a transform is active.
Show Ghosting
Ghosting is a method of displaying wireframe "ghost copies" of an animated object at a number of frames before or after the current frame. Use it to analyze and adjust your animation. Ghosts that overlap indicate slower motion; ghosts that are spread further apart show faster motion.
Show Key Times
Key Times shows the frame numbers along a displayed animation trajectory. Key times correspond to the settings in Time Configuration for Frames or SMPTE. By default, key times are shown as frame numbers.
Shade Selected
Shade Selected shades only selected objects in the scene.
Show Dependencies
While you are using the Modify panel, this command toggles viewport highlighting of objects dependent on the currently selected object.
Add Default Lights to Scene
This command opens the Add Default Lights To Scene dialog, which provides options that let you convert the default scene lighting into actual light objects.
Redraw All Views
Redraw All Views refreshes the display in all viewports. When you move, rotate, scale, or otherwise manipulate geometry, the viewports may display the scene with some irregularities, or with objects or parts of objects missing. Use Redraw All Views to redisplay your scene with all lines and shading restored.
Update During Spinner Drag
When Update During Spinner Drag is on, dragging a spinner (such as a Radius spinner for a sphere) updates the effects in real time in the viewports. Default=on.
Diagnose Video Hardware
This command runs a MAXScript script that displays information about your system’s graphic display configuration. This can be useful for telling you whether some interactive viewport features such as shadows are supported.
Expert Mode
When Expert mode is on, the title bar, toolbar, command panel, status bar, and all of the viewport navigation buttons are removed from the display, leaving only the menu bar, time slider, and viewports. Use Expert mode when you need to view your composition alone without the rest of the interface.
