That there is an example of one of my modded in soldiers.

This thread might be a bit old but I notice that the nationality of that solder is "can". That's not in the base game which means it was modded which means you might know how to do it.

Listen, I'm trying to make my own nationality. I have the sound files in sound/human/talk/rust. Rust is the nationality name.

It doesn't appear in the breed editor under nationality. If I try to edit the nationality through the breed files, the same thing happens - I crash when trying to select the soldiers in f3 mode.

I assume a file that has to be edited in order to work with a custom nationality? Please tell me what do I have to do.

I'm asking this here on an old thread because you look like you know what to do, and I can't find another place with this information.
