SimpleMarkerSymbols are being set to not visible, when any Polygon (like buildings or a Polyline) is between the SimpleMarkerSymbol and the Views Camera.
Is there any way to control the visibility by hand?
The use case is the following:
I am trying to depict waypoints for a path trough a city. And I always want to show those points, even when they are behind buildings or other graphics.
Unfortunately, this currently not possible and I cannot suggest any workaround.
It is in our backlog, though, not yet planned for a release. I'll write your use case down, thanks for sharing it!
By the way, are the buildings/polygons/polylines through what you'd like to see the symbols transparent or opaque?
