how to make packed_heightmap

[R.O.K.]

i am a noob modder i want to make a new accurate height map for vic 3 and now i have obtained a world height map for it. but there is also packed_heightmap.png file on map_data folder.
i pasted my new height map to map_data file but there wasn't any change in game. when i delete packed_heightmap, game doesn't show the topograhy. i have no idea about to convert my world height map like packed_heightmap file

If I remember correctly, you should be able to open your heightmap with the map editor, and that one can export the packed_heightmap. You start the map editor by adding -mapeditor in the launch options
