I'm trying to view 3D data in a scene. I can upload and publish Multipatch data over the web interface, but when I try to load it in a scene, I get "Multipatch Feature Services are not supported". When I try to publish the Multipatch data through Pro, it tells me it was successful, but when I try to open it in a scene in the browser, it tells me "Scene service is missing root node". Interestingly, I can look at the Multipatch data in a map view - but only see its boundingboxes.
When I try to publish an SPLK, the web interface just sits there for a while and then proudly tells me "There was an error". I get a bit more info when I try to go through Pro: "the data source is not supported", so I guess that would not work either way.
The server version is the latest available for download through my esri. I'm getting the same errors in a "manual" install (server, data store, webadapters and portal installed separately) as well as in an automatic one created by builder (ArcGIS_Enterprise_Builder_Windows_106_161855.iso). The Data Store is configured as relational and tile cache, so according to 00217: Multipatch layer cannot be published to current portal—ArcGIS Pro | ArcGIS Desktop, I should be able to use Multipatch.
I tried data in the following coordinate systems (EPSG): 4326, 3857, 31468. The data was created from scratch and displays properly in Desktop, Scene and Pro.
So what's wrong here?
