Having trouble visualizing data layers (new to ArcGIS Pro and the Maps plugin for Unreal)

Question

Have an error message in Unreal below for a Vector Tile Layer I uploaded to Arc Online

LogTemp: Error: ArcGISLayer status=Error name='01 CG_Zoning' message='Illegal state.' additional-message='The horizontal coordinate system (HCS) of the tiled source's spatial reference must match the HCS of the document's spatial reference.

Any tips on how to fix this? I tried imputing different Spatial Reference WKIDs aside from the default 4326. My Lat/Long coordinates in Unreal seem to be correct.

Hey James,

I wonder if you found a solution for this? I think I am having the same issue. Even though I added my 3D buildings, I am not able to add any other 3D data to my Unreal Project. I am testing it with, for example, OSM 3D trees but they are not visible. I wonder how did it go in your project?

Update, Oh I was able to visualize my data layer by having No Basemap. I think my issues related to Item Number 4 in the Troubleshooting Guide https://developers.arcgis.com/unreal-engine/faq/. Curious If/how I can have Basemap though and my data.
