Hi @wycgis, The 3D Tiles reader is auto-generated from 3D Tiles spec, as specified in [cesium-native/3dTiles.json at main · CesiumGS/cesium-native · GitHub](https://github.com/CesiumGS/cesium-native/blob/main/tools/generate-classes/3dTiles.json) and [cesium-native/package.json at main · CesiumGS/cesium-native · GitHub](https://github.com/CesiumGS/cesium-native/blob/main/tools/generate-classes/package.json). What are you trying to do with the 3D Tiles reader? There may be an easier way to approach this. -Alex ---
