Hi Brad!
I´m not rellay sure but maybe the network proxy is responable for not getting data from this (arcgisonline) url.
And:
I using a map in 2D/UtmProjection and scene in 3D/WebMercatorProjection. I can switch between them.
Of course i like to process events like the mouse moves identical.
I had to be aware the screenToLocation return values depending on the current projection. In 2D/UtmProjection my map has a wkid=32632; the same region in 3D/WebMercator has wkid=4326.
I use GeometryEngine::project to project the Esri::ArcGISRuntime::Point returned from screenToLocation to the desired SpatialReference.
Please have a look at
- the wkid of aour map, scene
- try to project the values.
(But attention, SceneGraphicsView::screenToLocation is expensive. I limit the computations to 4 times per second on my own)
Hope this helps!
Norbert
