I found this article:http://falloutmods.wikia.com/wiki/FO2_Worldmap_Editor Useful tool, but... I did not find any download link in Google. Do anybody know, where to download it?
Cubik never released / finished it. I still have some early version of it somewhere on my HDD, but no idea if I am allowed to give it out.
Here is a link to worldmap editor, still unfinished/a little buggy but newer version than Lexx has: http://newfmc.pl/cubik/fo2_worldmap_editor_alfa_2_release.zip all files must be in <game directory>/Data/Data and there must be files: city.txt maps.txt worldmap.txt the tool make changes only to worldmap.txt, make backup of this file before run program.
