I am working on adding 3D functionality to an existing runtime application. I am on version 100.3 of the SDK. I am trying to create a SceneView with a Basemap from local files as the app is built to work completely disconnected from the internet. The Basemap.Create... static methods require an internet connection. I have tried creating a local basemap with the new Basemap(Layer) constructor, as well as passing a Layer as a BaseLayer or a ReferenceLayer. In all attempts all I got back was a blank globe with grid lines.
Is it possible to add local files as a basemap in a sceneview?
