Export (not import) heightmap from the Editor

[Ancient Naturalist]

Hi everyone,

I’m currently working on a map of Persepolis. I’ve used DEM data for the landscape and traced the river in the region on a grayscale image. I’d like to add a tributary river, but since I’ve already made changes to the elevation in the editor, I can’t simply re-import the original grayscale image (plus the tributary river) without losing my progress.

Is there a way to export a grayscale elevation image from the editor or directly from the .pmp file so I can continue working on it?

Thanks in advance for your help!

Not that I know of, but it should be possible to write a python script that reads the height map and generates a texture. I wrote an importer for PMP in Godot that way.
