Suggestion for a short goal

Hi,

We are a group of 3 and we are working on a short goal of mimicking one specific traffic scenario in CARLA, a specific roundabout from OpenStreet MAP. We’ve tried exporting the map from OpenStreet to Carla, but the rendering and accuracy compare to real life is far from an acceptable state.

Looking at other forums, it appears as we need to learn UE4 or other 3D software, however, sadly none of the group members has any prior experience in the design-related software.

We are bound by a deadline of 10 days to finish the task and therefore we are seeking for suggestions of what we can best do.

These are the warnings shown when I converted OSM to OpenDrive format for map generation in CARLA.

Thank you.
