Example line with a path to an audio file: "audio_cue": "/SE/Weapons/structure/laser_defence_fire", But audio files are found inside /pa/audio inside of .fsb files. So, the question is If we add audio files to mods and put them in /SE/Blah/Blahblah, will the game use them?
Those are internal paths inside the fsb files (as defined in the fav file). Just shadowing that path doesn't work. We also can't create/alter these without the FSB project file that Uber use, or at least knowledge of the settings required, though admittedly it's been a while since I last tried.
