Structure

Field(s)	Description
Header	See Header.
u64 editor_map_id	Not sure what this does. Seems to change with each editor session.
struct start_placement	Sets the start position for preview mode. Field(s) Description float4 position Start position for the Run Map feature in the editor. The first three values are the global XYZ coordinate of the spawn point, and the fourth is ... something else. quaternion rotation Start rotation.
u32 game_tag	Don't know. Always 0xB2C0C0DE (2998976734)?
float time_compression_normal	Sets the map scale outside City areas.
float time_compresion_city	Sets the map scale inside City areas.
u8 europe_map_ui_corrections	Boolean; is enabled in europe.mbd. Nobody seems to know definitively what this does, but I'm guessing it might be related to Britain having a different scale in ETS2.
