I am using ArcGIS Enterprise Server 10.8.1, standalone without a Portal. I also have ArcGIS Pro 3.2 and ArcMap 10.8.2.
In my ArcGIS Pro, I have some DEM .tif files under "2D Layers" with custom color ramp and those same DEM .tif files in "Ground" for the 3D elevation. I followed this blog: https://www.esri.com/arcgis-blog/products/3d-gis/3d-gis/creating-and-using-elevation-layers-in-arcgis-online-arcgis-pro/
I want to share this whole scene as an Image Service to my standalone Server so that this service can be used inside SceneView in my JS code.
Thus I have 2 questions:
1. Without the Portal, the Web Scene button under Share is grayed out. Is there a workaround?
2. I was able to publish those same DEM .tif files in ArcMap to my Server as a Map Service. Do you know if Map Service will be usable for 3D terrain in SceneView.
