I’ve an application that shows both dynamic billboards and dynamic primitives in a map. All these graphical components have a height and Cesium respects the z-order when the view is using the SCENE3D.
But when I update the scene to a COLUMBUS_VIEW, the z-order is not respected. It seems that all the billboards are drawn first and then Cesium draws all the primitives. The effect is that is not possible to see a billboards over a primitive (I know that the height is correctly defined because in 3D it works fine). It seems that all the billboards are clamped to the surface (despite of I’m using the heightReference property).
I’ve also tried to reproduce the error in the SandCastle without success. Anybody has an idea about where the problem is?
