 #### Fixes :wrench:
 * Fixed bug causing billboards and labels to appear the wrong size when switching scene modes [#6745](https://github.com/AnalyticalGraphicsInc/cesium/issues/6745)
+* Fixed a bug that was preventing 3D Tilesets on the opposite side of the globe from being occluded [#6714](https://github.com/AnalyticalGraphicsInc/cesium/issues/6714)
