Custom BaseMap and Elevation are not visible

[WH1981]

Hello,

I have a question. I have a webscene with the 4326 coordinate system. With a custom elevation and basemap. See link below:

https://hasuniversity.maps.arcgis.com/home/webscene/viewer.html?webscene=9f46292852044481a2b789029ed...

Now i want to use the custom basemap and elevation url from the webscene in my code:

public ArcGISPoint geographicCoordinates = new ArcGISPoint(24.743406, 59.433131, 0, ArcGISSpatialReference.WGS84());

public void CreateArcGISMap()
	{
if (APIKey == "")
{
Debug.LogError("An API Key must be set on the SampleAPIMapCreator for content to load");
}

// Create the Map Document
// You need to create a new ArcGISMap whenever you change the map type
arcGISMap = new Esri.GameEngine.Map.ArcGISMap(arcGISMapComponent.MapType);

// Set the Basemap
//arcGISMap.Basemap = new Esri.GameEngine.Map.ArcGISBasemap(Esri.GameEngine.Map.ArcGISBasemapStyle.ArcGISImagery, APIKey);
arcGISMap.Basemap = new Esri.GameEngine.Map.ArcGISBasemap("https://tiles.arcgis.com/tiles/OPBDDktsPZ4DVPSk/arcgis/rest/services/Scene3_WGS1984_WTL1/MapServer", APIKey);

// Create the Elevation
//arcGISMap.Elevation = new Esri.GameEngine.Map.ArcGISMapElevation(new Esri.GameEngine.Elevation.ArcGISImageElevationSource("https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer", "Elevation", ""));
arcGISMap.Elevation = new Esri.GameEngine.Map.ArcGISMapElevation(new Esri.GameEngine.Elevation.ArcGISImageElevationSource("https://tiles.arcgis.com/tiles/OPBDDktsPZ4DVPSk/arcgis/rest/services/Scene3_WGS1984_WEL/ImageServer", "Elevation", ""));

But i get a empty map with no errors.

When i use this i it works.

// Set the Basemap
		arcGISMap.Basemap = new Esri.GameEngine.Map.ArcGISBasemap(Esri.GameEngine.Map.ArcGISBasemapStyle.ArcGISImagery, APIKey);
		//arcGISMap.Basemap = new Esri.GameEngine.Map.ArcGISBasemap("https://tiles.arcgis.com/tiles/OPBDDktsPZ4DVPSk/arcgis/rest/services/Scene3_WGS1984_WTL1/MapServer", APIKey);

// Create the Elevation
arcGISMap.Elevation = new Esri.GameEngine.Map.ArcGISMapElevation(new Esri.GameEngine.Elevation.ArcGISImageElevationSource("https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer", "Elevation", ""));
//arcGISMap.Elevation = new Esri.GameEngine.Map.ArcGISMapElevation(new Esri.GameEngine.Elevation.ArcGISImageElevationSource("https://tiles.arcgis.com/tiles/OPBDDktsPZ4DVPSk/arcgis/rest/services/Scene3_WGS1984_WEL/ImageServer", "Elevation", ""));

I think it's something with the basemap.

Can someone help me?
