I’m having an issue with large polygons rendering incorrectly. Looking at this closed issue, Large polygon rendering/fill issue · Issue #4871 · CesiumGS/cesium · GitHub, it seems like it should have been resolved (also see this article requesting users to try using large polygons: Large Polygons in CesiumJS – Cesium ). I left a comment at the bottom of that issue (Large polygon rendering/fill issue · Issue #4871 · CesiumGS/cesium · GitHub) with example data that does not render correctly and would appreciate any help in figuring out how to get this to work.
Thanks!
