It seems to be dlc+country, IE: Black Sea Unit Pack+Circassia: blacksea_circassia_gfxĮdit: i seem to be unable to get it to work manually without the mod active, perhaps there is something in the mod that enables the change to work, it needs further testing to see whats causing it, but im not a modder myself, so meh. Next part is to find out what all the graphical_cultures are called, we know westerngfx and mesoamerican_aztec_gfx. I havent experimented with it enough to know if there is any consequences to changing it, but it appears to be playable, and since its only listed once in the savefile its easy to find and change. I saved the savefile, went back to the game, loaded the savefile, et voila, western units. Almost 10,000 years of history is maybe too much history for anyone to handle, but if you’ve got the time, go for it. In this instance is changed the 'mesoamerican_aztec_gfx' to ''westerngfx'', which i happened to know was the code for basic western units. EU4’s most absurdly ambitious mod, Extended Timeline expands the scope of the game to cover everything from 2AD onwards, all the way up to the year 9999. The part which matters is the: graphical_culture='mesoamerican_aztec_gfx', that is what defines what your units look like. Graphical_culture='mesoamerican_aztec_gfx' You have to search for a bit of code about your nation, its pretty much near the end of the page, and looks like this: The national ideas provide every bonus possible through the nation designer at a higher than normal rate.

The mod provides a set of zero-cost custom national ideas which can be selected when creating a custom nation with the nation designer.

I started the game and saved, then i opened the save file. This is a cheat mod updated for EU4 v1.16.3. I created a new nation using the mod named above,''baghdad'', i chose aztec as their units, so it was easy to find for me in the files. More importantly, i seemed to have found what defines a nations unit models in its savefile: The mod is called Nation Designer Extender.
