Modifying ArcGISMap Component by C# script doesn't update Component in Inspector

Dear all,

While working on C# scripts to build a scene I noticed that changes made by the script to basemap and elevation settings are not mirrored in the ArcGISMap Component after the script has been run. Functionality is fine, but it's somewhat confusing that the Inspector data in basemap and elevation sections do not change at all.

Thanks and best regards

My environment:

Windows 11 Pro, Version 23H2

Unity 6 (6000.0.23f1)

ArcGIS Maps SDK for Unity 1.7

This is what the Inspector looks like with ArcGISMap GameObject selected.

No basemap and elevation source is disabled.

Code snippet from C# script

private void CreateArcGISMap() { // Initialize Map arcGISMap = new ArcGISMap(arcGISMapComponent.MapType); // Set the Basemap arcGISMap.Basemap = new ArcGISBasemap(ArcGISBasemapStyle.ArcGISImagery, APIKey); // Create the Elevation ArcGISImageElevationSource arcGISImageElevationSource = new ArcGISImageElevationSource ("https://elevation3d.arcgis.com/arcgis/rest/services/ WorldElevation3D/Terrain3D/ImageServer", APIKey); // Set the Elevation Source Name arcGISImageElevationSource.Name = "TestElevation"; // Enable the Elevation Source arcGISImageElevationSource.IsEnabled = true; // Assign the Elevation Source to the ArcGISMap arcGISMap.Elevation = new ArcGISMapElevation(arcGISImageElevationSource);

After running the C# script everything’s fine. Most importantly basemap and elevation are obviously applied in the Game View window.

But the Component isn’t updated at all (please see screenshot).

However, if the elevation is disabled in the C# script like so

arcGISImageElevationSource.IsEnabled = false;

it shows in the scene when the script is run again. So the functionality seems to be fine but the updated values are not shown in the Component itself.
