UE4 Quick Settings

Quick Settings

Level Editor

The Quick Settings are a set of properties for controlling selection, editing, and previewing aspects of the Level Editor. These can be accessed in the Level
Editor Toolbar.

Option	Description
Selection
Allow Translucent Selection	If checked, clicking on geometry with translucent materials applied will select the Actor. Enabling this option makes it possible to select meshes that are transparent, such as glass objects. Disabling the option can be very helpful in other cases, like in the case of a room filled with translucent particles. Selecting other objects in the room would be difficult otherwise since clicking on the particles would select the Emitter Actor.
Allow Group Selection	If checked, selecting an Actor in a group selects the group instead of the individual Actor.
Strict Box Selection	If checked, an Actor must be completely within the marquee selection box in order to be selected.
Editing
Show Transform Widget	Toggles the visibility of the Transform widget in the Viewports.
Draw Brush Marker Polys	If checked, semi-translucent polygons are rendered for the faces of a CSG brush when selected. Enabled Disabled
