The Editor Mode allows you to visually navigate and edit your scene in the Unreal Engine Viewport during the editor time. When you click the Play button, the simulation begins.
When the Editor Mode is enabled, ArcGIS Maps SDK for Unreal Engine loads ArcGIS Map content into the Viewport without playing the level. This mode is useful when you place an object in the level for example.
For more information about the Viewport, see Unreal Engine 5.0 Documentation: Using Editor Viewports.
To enable or disable the Editor Mode:
The Models Panel UI is synchronized with the ArcGIS Map Actor. Click on the Settings tab, and find checkboxes to enable or disable the settings. The Editor Mode option is enabled by default.
Click on the ArcGIS Map Actor in the Outliner panel. Then find the Editor Mode section in the Details panel. The Enable Editor Mode option is enabled by default.
You should have an Actor that has an ArcGIS Map Component attached in your level to work on a GIS scene. The option to enable or disable the editor mode is accessible from the ArcGIS Map Component. You can call the Set method and set the status (true or false) accordingly for the ArcGIS Map Component and use it together with the Create method. By default, the option is enabled.
