I'm trying to convert my GDB model, which is created in City Engine, to Cesium 3d tiles. Both reader and writer are implied with default settings. The transformation process is fine, what I found is the output models are grouped in different set. So every time I click a model, a group of models are triggered.Also, after exporting to Cesium 3D Tiles, the models in the same group share the same properties from first object in tile.
What I am looking for is to keep the original amount of models after transformation, so they are independent and hold their own attributes. What settings are needed to make it work for me?
