[carla-9.5] Fatal Error !! while executing generate_map.py for importing new maps in carla

[Dhairyashil-kpit]

Dear all,

I am new to Carla and simulation software. I am trying to import new maps in carla_9.5, I refer many issues related to import maps in carla, but I didn't got any satisfactory process for importing new maps in carla.

There are two process to import maps in carla:

1. Manually load maps via unreal engine ref: https://carla.readthedocs.io/en/latest/how_to_make_a_new_map/
2. Automatically load maps via python script: ref: https://carla.readthedocs.io/en/latest/generate_map_from_fbx/

I followed Automatic process to load new maps in carla using generate_map.py script:

1. Downloaded sample maps from OpenDrive : http://www.opendrive.org/tools/Crossing8Course.zip
2. Generated the FilmBox .fbx files using above xodr file using RoadRunner.
3. Then created directory with same name as xodr and fbx files inside RoadRunnerFiles of carla repo.
4. Then executed the python script: Util/generate_map.py
5. and getting Fatal error!! please refer log

I am not able to understand the proper process for importing new maps in carla. So please help me.

Thanks in advanced.

Hi @Dhairyashil-kpit ! I'll look into it. Could you provide with the fbx so we can reproduce the exact case?

[Dhairyashil-kpit]

Hi @dnovillo-CVC ,

I work with Dhairyashil. Kindly refer the attached .tar.gz file which includes :

1. .fbx file
2. .xodr file

However, I am not able to attach the assets as it is exceeding the size limit. Kindly use the .xodr file and open it in RoadRunner and the export it into .fbx to get all assets.

Hi @Dhairyashil-kpit . Thanks for your feedback. We have, potentially, solved the issue. We are submitting a PR asap to add the code fixes.

Hi @dnovillo-CVC, Could you provide more or less the date of the PR? I have the same problem and I would like to know when approx. it will be fixed. Thanks!
