Road Mark Attribute

Adds a Mark attribute to a road lane; it is used during baking to generate road markings. Each Attribute Key is assigned a road-marking type via Profile, or you can create a new type on the spot (Profile Source → Use Custom). To remove markings for a stretch of the lane, set Profile to empty.
