Is there a specific way to draw tunnels in RoadRunner?

Is there a specific way to draw tunnels in RoadRunner? I know how to adjust the elevation of roads, but I am looking for a way to create "tunnels".

Also, is there a way to visually see vehicles passing through underground road? When vehicles go through an underground road, they are blocked by the road or terrain above, and you can’t see them until they come out. Is there a method to see the vehicles in such situations, like making the road transparent or something similar?

Hey Jonghoon,

At this moment, Roadrunner does not support OpenDrive tunnel objects and also doesn't have a explicit way of modelling tunnels.

I think there is a workaround for your first question. Copy a new extrusion asset by duplicating a highway boundary wall and edit the shape in the 2D editor to match your desired tunnel shape.
