Curious if anyone knows where to find the audio files from vendors in the game files (I believe there is a western midi style clip at the stables and the fishing has a reggae loop)
As well, does anyone know what type of file extensions are? Ogg?
Any help greatly appreciated

I have other small question in here. Can we somehow like this vendors play other music to the outpost/banditcamp if add the music file in the same format to the server or not possible at all?

No as its client side

No as its client side

So, even with the SDK or Rust edit this could not be a thing?

to change the music no.
