I am not aware of any flag in the *.img format that could be used to mark a tunnel as such, but maybe it exists and nobody found it until now.

Betreff: [mkgmap-dev] Hide tunnels and other features in basecamp 3D mode
I added the DEM / Hillshading to my maps. If I set basecamp to show in 3d you get very nice results ! Thx for all the work done there.
Is there an option to tag certain elements to be hidden in (basecamp) 3D modus?
For example the Mont Blanc Tunnel goes straight up to the to the top 😊
