+ | For importing the Cesium 3DTiles format one additional file, next to the .json file which describes the structure of the tiles, a .3DTiles file needs to be created. | ||
+ | Next to the XXX.json file create an XXX.3dtiles file which has the same naming as the JSON file. | ||
+ | |||
+ | Import or drag and drop this file into Orbit will visualize the Cesium 3DTiles. In the desktop Content manager, the Cesium 3DTiles can only be visualized in the MapGL component. | ||
