Hello Cesium community.
I have done several tests with clamped polygons in Cesium and I see behavior that I am not sure is desired. Or at least it should have the option to disable it.
I use Viewer with the globe enabled, above 2000 meters high I have a 3D-tile that corresponds to a terrain photogrammetry.
On that 3D-tile I have placed a yellow polygon clamped to ground.
Indeed, the polygon is shown as clamped to the 3d-tile, but it is also shown as duplicate clamped to the globe. See Figure.
Is that a bug or a desired functionality?
In my case it is not desired, I would like to be able to remove the duplicate on the globe.
