Toggling the visibility of the grid, level objects, and gizmos unclutters the Level Viewport, letting you easily layout your level.

To show or hide the grid

1. In the menu bar, select Edit, then enable or disable Grid (Hotkey: G).
   The grid is displayed/hidden in all view panels.

To show or hide objects

1. Do any of the following:

   • Select an object(s) in the Level Viewport or the Explorer panel, then select Edit > Object Visibility > Hide\Unhide Selected (Hotkey: H).
   • In the menu bar, select Edit > Object Visibility > Hide Unselected (Hotkey: Alt + H) .
   • In the menu bar, select Edit > Object Visibility > Unhide All (Hotkey: Ctrl + Alt + H).
     

   The object(s) is displayed/hidden in all view panels, and its visibility icon turns blue in the Explorer panel.

To show or hide gizmos
Gizmos are objects that assist in level building, but aren't visible in game play. For example, the geometry of lamps, triggers, and cameras are visible when creating a level, but aren't displayed in the game.

1. In the menu bar, select Edit, then enable or disable Gizmos.
   The gizmos are displayed/hidden in all view panels.

To show or hide gizmos per view panel

1. Click the View HUD in the Level viewport, then enable or disable Gizmos and/or Grid.
   When a gizmo is hidden using the View HUD, its visibility icon turns orange in the Explorer panel, indicating it is only hidden in the currently selected view panel.
