Selection
| Option | Description |
|---|---|
| Allow Translucent Selection | If enabled, clicking geometry with translucent Materials applied selects the Actor. Enabling this option makes it possible to select transparent meshes, such as glass objects. Disabling it can be useful in other cases. For example, if you have a room filled with translucent particles, selecting other objects in the room would be difficult with this option enabled because clicking the particles would select the Emitter Actor. |
| Allow Group Selection | If enabled, selecting an Actor in a group selects the whole group instead of the individual Actor. |
| Strict Box Selection | If enabled, an Actor must be completely within the marquee selection box in order to be selected. |
| Box Select Occluded Objects | If enabled, marquee box select operations also select objects that are occluded by other objects. |
| Show Transform Widget | Toggles the visibility of the Transform widget in Viewports. |
Scalability
| Option | Description |
|---|---|
| Engine Scalability Settings | Provides quick access to Scalability settings that control the fidelity of various rendering features. Enable the Monitor Engine Performance? option to see how changing this settings affects your project's performance in real time. |
| Material Quality Level | Sets the Material quality level used for previewing in the Viewports. See Material Quality Switch Expression for more information on setting up Materials to work with this setting. |
| Preview Rendering Level | Sets the rendering level used by the editor. You can restrict rendering quality to device-specific capabilities, including different version of:

| Distance | Sets the distance Actors must be within in order to snap to one another if Enable Actor Snapping is enabled. |
| Enable Socket Snapping | If enabled, Actors can snap to sockets. |
| Enable Vertex Snapping | If enabled, Actors snap to the nearest vertex on another Actor in the direction of movement. |
