Entity geometry outlines are unsupported on terrain. Outlines will be disabled.

I am trying to make a polygon with an outline on terrain. Will this ever be supported in the future? Attached is a sandcastle example of me trying to change the color and add an outline. Windows 10, latest Chrome, Cesium 1.55.

I can comment the part in the code that disables the outline and it will draw but I don’t know what that may break down the line.


This is definitely a feature that has been requested a lot, see:

I would bump that issue to convey your interest and keep up to date with any updates. It looks like there’s already some work done to support this but there’s a few more problems to solve to get it to work well in the general case.
