Quick Overview

The command reload_heightmap in Europa Universalis IV is used to reload the game's height map.

A heightmap in EU4 refers to the 3D map of the game world that determines the terrain height.

So, if there were any changes made to the heightmap while the game was running, this command would update the game to reflect those changes.

In-Depth Description

The reload_heightmap command in Europa Universalis IV (EU4) is a console command that is mostly used during the game's development or modding.

When you execute this command, the game's engine re-renders and reloads the map's heightmap.

A heightmap in gaming terminology is a grayscale image used to produce a 3D terrain map. A darker pixel indicates lower elevation, while a lighter pixel indicates higher elevation.

Therefore, the heightmap is responsible for the topographic variations you see in the in-game terrain, like mountains, valleys, plateaus, etc.

In EU4, this command essentially forces the game to redraw the 3D topographic map, with any changes you might have made to the heightmap file during a gaming session.

This can be extremely useful in game development or modding because it allows developers and modders to see the immediate effect of their changes to game's world terrain without restarting the game every time they make a modification to the heightmap file.

This command can save a significant amount of time and can immensely improve the workflow.

How to Open the Command Console

In EU4, cheats are executed from the command console, a text box that you type commands into.

To open the command console press the ~(tilde) key, which is typically located under ESC (escape).

If your keyboard does not have that key, or pressing ~ does not work, try the following keys:

  • ~
  • SHIFT + 2
  • SHIFT + 3
  • ALT + 2 + 1

Type your command into the console, and then press ENTER .
