Because it was designed for version 1.5, it is considered outdated for current versions of HOI4. To make maps work in 2024–2026, modders typically have to use external tools like Astro's HOI4 Map Gen Tools to fix output files or manually update common game files using Notepad++ .
Version 2.3 is expected to introduce thermal erosion simulation and tectonic plate modeling, moving from pure noise‑based generation to geologically inspired algorithms.
Modders typically follow a specific pipeline when using MapGen 2.2:
: Creates the 3D relief of the world (mountains and hills).
