Carla Export from RoadRunner scene is not showing all assets and much more details

Hi folks,

I’ve been testing RoadRunner exports to CARLA for autonomy testing—specifically with code repos like PCLA. Unfortunately, the export format (FBX + OpenDRIVE) doesn’t fully meet the requirements, and only the sample maps seem usable for actual autonomy testing.

Has anyone had a similar experience?

Hi @Nastaran Saberi,

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!

Also, I hope you have already installed the basic RoadRunner importer and the CARLA integration plugin. if not feel free to use the following link,
