I understand that when exporting from RoadRunner to Carla, some assets and details are missing, resulting in incomplete or inaccurate export results.
Since you are currently exporting to the CARLA Filmbox format, I recommend trying the CARLA (.udatasmith, .xodr) export option available in the same export dialog as a workaround. Please note that exporting to Unreal Datasmith requires downloading Unreal Engine. You can find more information about Unreal Datasmith export requirements at the following link:
Additionally, when exporting maps for CARLA from RoadRunner, I highly recommend following the steps outlined in this documentation:
Pay special attention to the "Export a map in RoadRunner" section, particularly regarding connections and geometries, as slight gaps in meshes can occur due to aggressive turning angles.
Furthermore, adjusting the "Export To Tiles" options in the export dialog can sometimes improve export performance and stability.
I hope these suggestions help resolve the issue. Thank you!
