What you need

First of all - idea :)

And some software to convert your glorious heightmap to format recognized by "Soviet republic"

Update: Since version 0.7.9.8 Map Editor allow to import greyscaled PNG file :) so part about converting image to DDS format is obsolete :)

I recommend two free tools:

- GIMP + DDS plug-in
- Paint.net + DDS2 plug-in

User @Lac_M (thanks!) recommends Nvidia tool for dds textures:

How to generate heightmap?

You can make heightmap from scratch, or you can generate heightmap based on real terrains.

I prefer two sites:
http://terrain.party/ or
https://tangrams.github.io/heightmapper/

Both sites are easy to use. You need to export image from this site in any format (jpg/png).

In this tutorial I choose part of San Francisco Bay :)

When you export image from these sites, in graphics editor you have to prepare this file for Soviet Republic World Editor.

Working with graphics editor

World Editor use 2048*2048 pixels heightmap, so you need to resize your file to these dimensions. Then change image mode to greyscale.

And remember:

Darker = lower terrain
Brighter = higher terrain

When you finish your heightmap, you have to do one, little thing before you export file.
You have to make 2 pixels width, black border. Without this border you can see some visual glitches on map borders in game.

Now you can export .dds file. Format of .dds file:

R32F, no MIPmaps (you can try to export in BC1/DXT1 format of similar but users report that sometimes it makes problems while editing)

How to convert .png to .dds R32F using Nvidia Texture Tools?

After installing tools, in command line (cmd) run command:

nvdtx -quality_highest -file <path_to_png_file> -fp32 -outdir <path_to_output_dir>

For example:

nvdxt -quality_highset -file e:\maps\mymap.png -fp32 -outdir e:\maps\

It generate R32F DDS file mymap.dds in e:\maps\ folder

Working with World Editor

Now you can import prepared DDS in World Editor.

But…. What is this? Terrain looks like from “Minecraft” :)

It’s typical - don’t worry. After importing, use terrain smoothing tool to improve quality of your heightmap.

Optionally you can scale and offset your terrain.

Be creative :)

And this for Mirroring your Image (if features are on the wrong side of the map)

I have noticed that many times, people do not know to save/update their workshop map *after* importing the terrain to the workshop item. This results in the workshop item not containing the terrain files (<1mb file size shown).
Would be a great help for new mapmakers and everyone who subscribes to workshop maps if a small section could be added to the guide explaining this vital step in publishing a map on the workshop.

How do you deal with rivers? I tried to do black lines according river map, but that makes very steep shore.

Is it possible to edit in a photo editor an already created map? I am trying to edit the heightmap.dds, but I'm getting errors while trying to open it in gimp or online .dds editor

Terrain.party has been non-functional for a while now, but I did recently find a similar website that has similar functionality: https://cs.heightmap.skydark.pl/

hi all - i found a bug[?] perhaps where in GIMP if you export as .dds, and then import heightmap into terrain editor, it will flip the image, so i just correct that in GIMP. thanks for the guide, very useful to get me going! :)

just so that people are aware Paint.net no longer requires a plug in. read update notes here.
