Problems loading custom elevation layers and IntegratedMesh data

Hi,

In the latest ArcGIS maps SDK release 2.1 I am having issues loading in custom elevation data and IntegratedMesh data through C# API. It worked in prior 1.* without an issue so there seems to be a problem in the latest release. I use the following code:

Map is created as follows which is called in start:

private void CreateArcGisMapComponent() { GameObject go = new GameObject("ArcGISMap"); _mapComp = go.AddComponent<ArcGISMapComponent>(); _mapComp.transform.SetParent(transform, false); _mapComp.OriginPosition = new ArcGISPoint(Origin.Longitude, Origin.Latitude, Origin.Altitude, ArcGISSpatialReference.WGS84()); _mapComp.MeshCollidersEnabled = _enableMeshColliders; _mapComp.MapType = _mapType; _mapComp.MapTypeChanged += new ArcGISMapComponent.MapTypeChangedEventHandler(() => CreateArcGISMap()); GameObject rebaseObject = new GameObject("Rebase Component"); rebaseObject.transform.SetParent(go.transform, false); _rebaseComponent = rebaseObject.AddComponent<CustomRebaseComponent>(); if (ApplicationBootstrapper.Instance.IsDebugEnabled(typeof(TerrainManagerHostService))) { ArcGISViewStateLoggingComponent logger = _mapComp.gameObject.GetComponent<ArcGISViewStateLoggingComponent>(); if (logger == null) { _mapComp.gameObject.AddComponent<ArcGISViewStateLoggingComponent>(); } } }

private uint CreateArcGISMap() { uint result = Res.OK; List<TerrainDefinition> definitions = _parser.GetDefinitions().ToList(); var map = new ArcGISMap(_mapComp.MapType); var elevationLayers = new ArcGISCollection<ArcGISElevationSource>(); var layers = new ArcGISCollection<ArcGISLayer>(); foreach (TerrainDefinition definition in definitions) { result = ValidateConditions(definition, out ArcGISMapLayer layer, out TerrainSource source); if (Res.CheckCallFailed(result)) { break; } string uri = source.Uri.IsFile ? source.Uri.LocalPath : source.Uri.ToString(); if (layer.Type == ArcGISSourceType.Basemap) { if (!string.IsNullOrEmpty(map.Basemap.Source)) { LOG.Error("A basemap has already been added, multiple basemaps are not supported!"); result = RES.E_SERVICE_INVALID_STATE; break; } if (layer.LayerSourceType == ArcGISLayerType.ArcGISImageLayer) { map.Basemap = new ArcGISBasemap(uri, ArcGISLayerType.ArcGISImageLayer, ""); } else if (layer.LayerSourceType == ArcGISLayerType.ArcGISVectorTileLayer) { map.Basemap = new ArcGISBasemap(uri, ArcGISLayerType.ArcGISVectorTileLayer, ""); } else { map.Basemap = new ArcGISBasemap(uri, ""); } LOG.Debug($"Added Basemap {Enum.GetName(typeof(ArcGISLayerType), _mapComp.BasemapType)} from URL: \"{uri}\""); } else if (layer.Type == ArcGISSourceType.Elevation) { var elevation = new ArcGISElevationSource(uri, ArcGISElevationSourceType.ArcGISImageElevationSource, ""); elevationLayers.Add(elevation); LOG.Debug($"Added Elevation layer from URL: \"{uri}\""); } else { layers.Add(new ArcGISLayer(uri, layer.LayerSourceType, "")); LOG.Debug($"Added {Enum.GetName(typeof(ArcGISLayerType), layer.LayerSourceType)} from URL: \"{uri}\""); } } if (Res.CheckCallFailed(result)) { return result; } if (string.IsNullOrEmpty(map.Basemap.Source)) { LOG.Warn("Missing basemap, creating an empty basemap"); _mapComp.Map = new ArcGISMap(ArcGISSpatialReference.WGS84(), _mapType); } else { map.Elevation = new ArcGISMapElevation(elevationLayers); } map.Layers = layers; _mapComp.View.Map = map; _mapComp.Map.LoadStatusChanged += OnMapStatusChanged; _mapComp.View.SpatialReferenceChanged += OnSpatialReferenceChanged; return result; }

And if i get it to load, my integrated mesh data can look like this and I need to move the camera around to get it to load:

Also, another issue which bothers me is that when I update the map through C# script, these changes does not update the MapComponent in the editor.

If i instead for example add the elevation source like this, it loads. So something funky is going on and it may be seperated from the issue I have with Integrated Mesh layer that in 2.1 sometimes does not render depending on angle of camera. If I downgrade to 2.0 and use the below code, everything works for me.

var temp = new ArcGISElevationSourceInstanceData { Source = uri, AuthenticationType = Esri.ArcGISMapsSDK.Authentication.ArcGISAuthenticationType.None, IsEnabled = true, Type = ArcGISElevationSourceType.ArcGISImageElevationSource, Name = layer.Name }; _mapComp.MapElevation.ElevationSources.Add(temp); map.Elevation.ElevationSources.Add(new ArcGISImageElevationSource(uri, layer.Name, ""));

For some reason when I load an elevation layer from an offline file I need to add it to elevationsources here meanwhile if i use a elevation source from an Enterprise/ArcGIS online server I need to add it to the map.
