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

• 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

Do any of the following:

• Right-click a unit in the Explorer panel, then select Hide Selected or Show Selected from the menu that appears.
• 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 and manipulators that show up in the editor's viewport to help you build your levels, but that aren't visible when you run your project in the engine. For example, light sources, reflection probes, triggers, and cameras are all visible when you're working on a level, but aren't displayed when you test your level or run your project.

• 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

• 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.
