I am facing issue with conversion of geojson data to cesium 3D tiles. I have tried converting geojson to cesium 3D tiles using FME software. When I convert using FME, some of the faces of buildings are missing (shown in the attached images). Kindly guide me if something missing in that conversion.
I have attached images of geojson data as well as cesium 3d tileset data from all sides of the building.
