I have a problem where there z-index or depth isn’t respected in cesium as can be seen in the image above.
The labels and the coloured icons where the tails are attached are both Billboards with a position that has a higher Z (Cartesian3(x,y,Z)) value than the tail which is a path. This happens in both Columbus and 3D views. Using Cesium 1.25.
The Z value ranges from -1 to 3. The billboards are closer to 3 while the path has something around 2.
If I set the Z value of the path to something much lower like -500 its still above the billboards. Same if I use the eyeOffset and set the value to something extreme its still not respected.
What can I do to fix this? Or is this part of the very famous transparency issue: https://github.com/AnalyticalGraphicsInc/cesium/issues/2130 ?
