Map format changelog

Changes to the map format that are known to me, starting with 900→901.

907 (1.59)

Curve

• Curve items have been reworked to allow up to four curve schemes to be placed by one item.

Cutscene

• There are two new cutscene types, "Tourist board" and "Point of interest".

DLC guard

• DLC guard values for Illinois and South Dakota (ATS) have been added.

906 (1.58)

Sign

• Sign items gain the ability to override sign board properties.

Vegetation Struct

• The vegetation struct used in several item types has an additional scale value: 180 to 200%.

905 (1.57)

DLC guard

• DLC guard values for Nordic Horizons (ETS2) and Louisiana (ATS) have been added.

Node

• In preparation for the upcoming Coach Bus and Road Trip DLCs, nodes have seven new flags for restricting which kind of vehicle a player can drive onto the parented roads or prefabs with.

Road

• There is a new flag, "center blocked".
• The data part gains four fields, right_edge_right_look etc., for specifying the look of the road's edge models.
• The edge override struct also gains a look field.

903 (1.55)

Bus Stop

• The item has been restructured to start with the new economy_link_item struct.

Company

• The item has been restructured to start with the new economy_link_item struct.

Road

• The data part has a new field, previous_length, containing the sum of the lengths of all road items connected to this one in backward direction.

Terrain

• There is a new field, previous_length, containing the sum of the lengths of all terrain items connected to this one in backward direction.

901 (1.51)

Curve

• The "low poly vegetation" flag has been renamed "low detail". When enabled, all models change into their low LOD variant instead of just vegetation like before.

Environment Area

• No Weather Area has been renamed Environment Area.
• This item has gained properties for setting the climate and reflection cube as well as a new flag for disabling precipitation.

Far Model

• There is a new "far shadows" flag.

Map Area

• Colors are no longer hardcoded, but an index into the map_area_* arrays defined in /def/map_data.sii.

Prefab

• Prefabs gain a "merge roads" flag which is labeled experimental.

Sign

• The sign item has new "no collision" flag.

Terrain

• Terrains now have a "adaptive tessellation" flag (initially called "superfine tessellation" in 1.51).
