Main Editor Toolbar

Overview

What follows is a brief description of the controls on UnrealEd's toolbar as they appear from left to right.

Maps

Create a New Level

Creates a new map, first prompting to save any open levels that are unsaved or that have changed since last save.

Open an Existing Level File

Opens an existing map, first prompting to save any open levels that are currently unsaved.

A list of the most recently opened maps is available by clicking on the adjacent button.

Toggle Map File As Favorite

Toggles whether the current map is saved as a favorite. A list of favorite maps is available by clicking on the adjacent button.

Save Current Level

Saves the 'current level' (as specified in the Level Browser). Only saves if the current level is unsaved or has changed since last save. If source control is enabled and the current level needs to be checked out from source control to be saved, you will be prompted to check out the package.

Save All Levels

Saves all levels are unsaved or that have changed since last save. Only saves levels in packages that are writable on disk. Does not prompt for checkout from source control.

Save All Writable Packages

Saves all packages which are writable and have been saved previously to disk. This will not prompt to checkout packages under source control and will not save new packages which do not already exist on disk.

Undo/Redo

Note: You cannot undo/redo after certain actions (e.g. opening a map, building a level, etc).

Undo the Last Action

Undo the last action in the transaction stack.

Redo the Previously Undone Action

Redo the last undone action in the transaction stack.

Widget

A tool that appears when actors are selected, the widget provides visible handles that can be selected and dragged to transform the selected actors.

Selection Mode

Toggles whether objects can be transformed. When enabled, objects cannot be translated, rotated, or scaled.

Use translation widget.

In translation mode, the widget will translate (move) the selected actors.

Use rotation widget

Sets the widget to rotation mode, in which selected actors will rotate about the pivot point.

Use uniform scaling widget

Sets the widget to scaling mode, in which selected actors will be scaled by a uniform amount in the X, Y and Z directions.

Use non-uniform scaling widget

Sets the widget to non-uniform scaling mode. In this mode, dragging the individual widget handles will scale the selected actors along specific directions. Note that activating the non-uniform scaling widget will automatically convert the widget's reference coordinate system to 'Local'.

Reference coordinate system

The reference coordinate system (RCS) specifies the frame of reference that widget operations will be applied. For example, when an actor has been rotated and the RCS is set to 'Local', translating the actor via the translation widget will result in movement along the actor's rotated directions rather than the global X/Y/Z directions.

Search

Find Actors

Opens the 'Search For Actors' dialog, which allows the user to find specific actors in levels that are currently visible in the Level Browser.

Browser

Content Browser

Opens the Content Browser, which allows the user to search for assets.

Editors

Matinee Editor

Allows the user to open any matinee sequences on the current level.

Viewport Camera

Distance to far clipping plane

Controls the far clipping plane distance in the perspective level viewport. The clipping plane moves closer to the camera as the slider moves left. Often an editor performance benefit when rendering perspective views of large, complex levels.

Selection

Allow Translucent Selection

Allows objects with translucent materials to be selected

Encompass to Select

When enabled, and object must be entirely encompassed by the selection box to be selected.
