Creating custom Overlays

Overlays

Unity authoring tools are available as Overlay panels in the Scene view window to make them more accessible and improve your workflow. You can customize which Overlays are shown, their placement in the Scene view window, and save your customized Overlay configurations as presets to reuse and share.

You can also create custom Overlays.

Displaying and hiding Overlays

  1. Click anywhere in the Scene view and select the Spacebar to open the Overlays menu.

Hiding all Overlays

Toggle all your configured Overlays to hide/show by pressing the backtick ( ` ).

Positioning Overlays

To reposition an Overlay in the Scene view:

  • Click and hold the handle (=) or click the header of the Overlay and drag it to the desired position in the Scene view.

Note: You can overlap Overlays that are floating in the Scene view. Click on the Overlay to bring an Overlay to the front.

Docking Overlays

To dock an Overlay to the top, bottom, or side of the Scene view:

  • Click and hold the handle (=) of the Overlay or click the header of the Overlay and drag it over the boundary of the Scene view until the boundary is highlighted in blue and release it. The Overlay will dock itself at the highlighted position.

To move an Overlay into a position occupied by another docked Overlay:

  • Drag the Overlay until the blue highlight indicates the desired position and release. The Overlays will rearrange themselves.

Note: An Overlay that is not a toolbar (for example, Orientation) will collapse when docked. Access the Overlay’s options by clicking the down arrow.

Collapsing and expanding Overlays

To collapse an Overlay, right-click the handle (=) or click the border of the Overlay and select Collapse.

To expand, right-click and select Expand.

Snapping Overlays

To snap an Overlay to a corner of the Scene view:

  • Click and hold the handle (=) of the Overlay and drag it to a corner of the Scene view until a blue highlighted square appears and release it.

Note: Snapping several Overlays into the corner does not snap them to each other. Each Overlay remains snapped to the corner until you change its position.

Changing Overlay orientation

Some Overlays allow you to select a vertical or horizontal orientation.

To change an Overlay’s orientation:

  • Right-click the handle (=) and select Horizontal or Vertical.
  • If the Overlay is floating or snapped in the Scene view, select Panel to change the Overlay into a named panel.

Saving Overlay configurations

You can save your Overlay configurations to easily switch configurations in your project.

To save your Overlay configuration as a preset:

  1. Press the spacebar to open the Overlays menu.
  2. From the drop-down menu, choose Save Preset.
  3. Name the preset and click Save.
    The preset is saved to the drop-down menu.

Note: When you save an Overlay preset in this way, it does not create a file that you can load to another project, but saved presets are available to any Unity project on your computer.

Overlay configurations are also saved when you save the Editor layout.

Switching Overlay configurations

To switch your Overlay configuration:

  1. Press the spacebar to open the Overlays menu.

  2. Choose an Overlay preset from the drop-down list.

    The Overlay configuration is shown in the Scene view.

Importing and exporting Overlay configurations

To import an Overlay configuration into your project:

  1. Press the spacebar to open the Overlays menu.
  2. From the drop-down menu, choose Load Preset From File.
  3. Browse to the preset .wpr file and click Open. The preset is added to the drop-down menu.

To export an Overlay configuration, save it as a .wpr file and then import it into another project:

  1. Press the spacebar to open the Overlays menu.
  2. From the drop-down menu, choose Save Preset to File.
  3. Name the preset and click Save. The preset is saved to a folder and in the drop-down menu.
