Excuse me, is the opendrive format supported by BeamNG.tech.v0.35.5.0 version of road editor 1.4 standard or which standard?
Thank you for your question.
You can refer to the list of unsupported features at BeamNG Disk Options documentation. The ASAM standard referenced should correspond to the version available no later than early 2024, around the time the tool was first released.
Hope this helps!
