Your province needs its general climate defined in climate.txt.

Your province needs an entry to define its continent in continent.txt.

Again, test frequently and make frequent backups The present author has made that mistake much more than once. If you use Paint or something that somehow messes with the colour map, you'll cause a crash at the worst and at the best your terrain will be buggy ( and have to get a fresh copy/backup of these two map files to start over). NB - These two files must be edited with a program like Photoshop or GIMP which will not touch the colour map.

If you're adding anything that messes with water, like adding new islands, expanding provinces into sea provinces, expanding sea provinces or adding new ones into land provinces, you must make the land/sea border match in both rivers.bmp and terrain.bmp.

If you're going to make lots of changes, test frequently and make backups to save yourself trouble. In GIMP, you should use the Export option and tick the boxes which fit the info in the previous sentence. If you want to use a more advanced image editing program, like GIMP or Photoshop, make sure that the file is saved WITHOUT colormap information and in a 24-bit BMP format.

Take that RGB code and use it to make your province wherever you like in provinces.bmp.

Paradox left several spare slots for the intrepid modder.

Add it in definitions.csv, where it's important that it have a unique RGB code and number.

Follow these instructions VERY CLOSELY, because if you miss something or don't do it exactly right, the game will not like it.

To add a new province to the game, you have to do each of the following. If you have any questions, corrections, or would like to add something, let me know! Notepad++ is ideal for editing the various text files that Vic2 uses. Hi guys, I've seen this question pop up a few times, and the only post I find in my cursory search is quite old (though still relevant), so I thought I would share how it's done.īefore you start, I suggest having GIMP or Photoshop installed, as those are your best tools for modding the map files.
