Landscape from a 2D reference image

Hello everyone.

I have a game project wich is an openworld.

I have a .jpg map image of the land and I know its scale (it represents an area about 40km by 20km wide) and I wonder:

  1. how do I set (or calculate the) the size of the landscape for it to be 40km by 20km wide.
  2. how I can use my image as a reference (somehow like what we do in blender) to create my landscape.

Thanks in advance.

Hey there @Laurent_Menten! Welcome back to the forums! So the answer somewhat depends on if you’re going to be using the new world partition system or the older world composition system. The setup changes just a little bit for each one.

Either way you’re going to need to have a height map and import it during level generation. Here’s a couple of tutorials that go over how to do that.

For this video you can ignore the Gaia portions since you have a heightmap ready. I’ve skipped to the part during import where he goes over how to determine the size of your map based on your heightmap and how large you want it.
