I am improving with b3dm-\>gltf.  
An error has occurred.

In addition, the site provides information  
An error occurs.  
**[3d-tiles-validator/tools at 2.0-tools · CesiumGS/3d-tiles-validator · GitHub](https://github.com/CesiumGS/3d-tiles-validator/tree/2.0-tools/tools)**

Is there a tool to convert b3dm-\>gltf?
