How to create a Height Map Mod

To create a new Height Map layer we need to replicate this path in our Mod:

[ModName]\Ancient\Entity\Global\Heightmap\[AreaName]

In the root folder of the mod we need the same files needed for every other Mods, see

How to create a Mod by hand

In the [AreaName] folder we need two files, the Heightmap.tif with the Geotiff data and an Index.art with the information of the covered area.

First you need to define the covering area of the height map by providing the latitude and longitude of the lower left point and the upper right one.

area

Then we put this information inside the Index.art file next to your Geotiff file.

 F32x4:
 {
 	Name:"Area"
	Value:"0,40,5,45"
 }
 
 Bool:
 {
 	Name:"Bathymetry"
 	Value:"true"
 }

The Heightmap.tif geotiff file format needs to be 16 bits uncompressed and may contains or not bathymetry info for underwater areas aside the mainland elevation data, set the Bathymetry accordingly.

The actual resolutions of our height maps files goes from 1800m/px the Basemap to 225m/px of the Europe Atlantic area.

Normally you need to increase this resolution in your Mods to mark the difference with the actual game height maps.

All the game and Mod height maps are ordered by resolution and merged to be used in game.
Also the first time a height map it’s read, we normalize his values, update the file, and marked as ‘backed’ inside the Index.art file.

Thanx for this,
Its posible to create heighmaps about a zone that is not in the “clear zone” of the world map?
Or we are able to insert the heighmap only in the iluminated area?
In my particular case, i want to import the heighmap about Canary Islands, but they are in the greyzone. I hope im explaining clear.

You mean outside of the playable region of the global map? I’m curious, what purpose will this serve?

The heightmap i want to import, is from a zone outside the playable area.

Ah so you are saying you want to important a heightmap from outside the playable area, and then put inside the playable area?

No, i want to import a heightmap from canary islands, wich are outside the playable area, and make it playable.

You can include this height map and then change mesolithic culture distribution texture.
