CityEngine generates models and exports GDB data with lost attribute information

[shijiushi]

Import GDB data into CityEngine, generate railway models through street, and then export GDB data format. However, it was found that the attribute values in the original GDB were lost. May I ask how to preserve the attribute information of the newly generated GDB data?
