In this window you can change the default preferences of the Sandbox Editor in order to customize the look and functionality of Sandbox. You can find the preferences under Edit -> Preferences.


Every page has a button called Reset to Default. This will reset all the values in that specific page to their default settings, e.g. if you're in Audio -> General, clicking this button will reset those settings to default, but not the ones in AI -> Navigation.

The search bar in the top left will let you search for topics in the left column.

Max Notification CountMaximum number of notifications displayed before they are combined into a single notification in the notification list.

Track View


UI refresh rate (fps)Defines the maximum refresh rate of the Track View window when the animation is active.
So if the animation speed is 30 frames per second, and the UI Refresh Rate value is 15 frames per second, the track-viewing will be updated approximately on every second frame of the animation.

Speed Height RelativeWhen enabled, adjusts the speed of camera movement based on the height of the camera above terrain or objects. The camera speed is multiplied by the height in meters (clamped to a range of 1-1000). This lets you move precisely when close to the ground, or quickly to different parts of the level, without constantly adjusting the camera speed slider.
Terrain CollisionToggles terrain collision on and off. When turned on, the camera does not go through the terrain when hitting it, but will always move along it. This option also affects Speed Heigh-Relative: when on, camera height is measured above terrain or objects; when off, terrain only.
Object CollisionToggles object collision on and off. When turned on, the camera does not go through objects on the terrain when hitting them, but will always move along them.
Movement SpeedThe movement speed of all movements made in the Viewport.
Rotation SpeedThe movement speed of the mouse while controlling the Viewport camera.
Fast Movement MultiplierFast camera movement speed multiplier when Shift is pressed and held, i.e. a value of 2 will double the movement speed.
Wheel Zoom SpeedThe movement speed of the mouse wheel camera zoom.
Mouse Wheel Behavior
  • Zoom - Mouse wheel will zoom only, just like in old legacy editor.
  • Change Speed - Mouse wheel will only change the movement speed
  • Zoom, Change Speed When Moving - (default) Mouse wheel controls the speed while zooming and zooms while stationary.
