I have a 3dtileset that no in latlong coordinate
when I rotate/zoom/pan it, the object disappeared. seems like move to other place in the world, I have to reload the page or zoomTo it again for displaying it again.
any ideas?
Are you able to provide Sandcastle code example (https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/) showing this issue?
It sounds like it might be the same issue as in this thread:

One solution is to fix the camera to that reference frame so that you can orbit and move but not lose it. Another solution is to move the tileset down to the surface of the Earth. This code example shows you how to adjust a tileset’s height:

Let me know if this helps.
