Projected coordinate system in Unity other than Web Mercator

Question

We have set up the ArcGISMap component using various PCS WKIDs other than Web Mercator but notice that no matter what we set the WKID to the overall shape / projection of the MAP in the Unity Scene is always the same and appears to be Web Mercator.

For our use case we need the map to have the 'shape' of the WKID we use so that the Map aligns with the Models we are bringing in to Unity that have been modelling to line up with the PCS they were modelled in and therefore don't align with the Web Mercator projected map.

What are the steps we need to take to have the map use a different projection?

Our wanted behavior is what is shown in your ArcGIS Pro web page regarding Supported Map Projections

Supported map projections—ArcGIS Pro | Documentation

Your understanding is correct and yes you can use Pro to project the data to new spatial references.

So here is a circular dataset for the artic https://www.arcgis.com/home/item.html?id=c7381cb155a043a2bba2b84566677262

You can see the content is maintained in its circle form but we are padding it with white tiles to make it a rectangle.

You can use the map's extent property to trim this down to just be the area without the white tiles

The way I read the documentation, I was under the impression that I could set the Map's Spatial reference (when in Local mode), then point it at your Standard Basemaps and have it re-project those basemaps into my chosen Spatial Reference's shape.

From my (updated) understanding, we'd have to provide a separate Map Server endpoint for each of the Spatial References we want to support.

Are we allowed / able to re-project sections your Standard Basemaps using ArcGisPro into the various projections and expose as separate end points?
