Random New World modding - Europa Universalis 4 Wiki (2024)

This article is timeless and should be accurate for any version of the game.

The Random New World (RNW) files are found within /Europa Universalis IV/map/random/.

Map Generation[edit | edit source]

The RNW generator uses several image files that supersede the base map:

• colormap_autumn.bmp
• colormap_spring.bmp
• colormap_summer.bmp
• colormap_winter.bmp
• colormap_water_base.bmp
• heightmap_base.bmp
• colormap_noise.bmp is used to add noise to the generated color maps for the RNW portion of the world.

It also makes use of several files for naming:

• RandomLandNames.txt controls the strings used to randomly name the RNW land provinces.
• RandomLakeNames.txt controls the strings used to randomly name the RNW lake provinces.
• RandomSeaNames.txt controls the strings used to randomly name the RNW sea provinces.

Tweaks[edit | edit source]

The tweaks.lua controls various constants that affect the RNW generator.

Options[edit | edit source]

Scenarios[edit | edit source]

The RNWScenarios.txt file contains all the possible scenarios that the RNW may use during generation.

Scenarios are applied per region, meaning once one scenario has been applied to a region, another one cannot.

Note: to allow colonial regions to be created, you need to make sure the colonial_placeholder_1, colonial_placeholder_2, etc. objects are present in 00_colonial_regions.txt.

Tiles[edit | edit source]

The RNW generator creates the RNW world by using predefined tiles for all land. Every tile has a configuration file that defines the various aspects of itself. The name of the configuration file is the name used by the tile data files.

Tile configuration is found in /Europa Universalis IV/map/random/tiles, with the tile data in /Europa Universalis IV/map/random/tiles/data.

Each tile has the follow image files, which follow the same standards the game map images do.

• <tile>_h.bmp - Height map
• <tile>_p.bmp - Province map
• <tile>_r.bmp - River map

It is important to note the function of the size attribute in a tile configuration file. The height and width of the RNW section of the world (by default 2304 by 2048) is divided into multiples of 128.

All tiles have a height and width that is a multiple of 128. So, for example if a tile was 256 pixels tall, and 128 pixels wide, it would have use size = { 2 1 }.
