I have recently started to add standalone vehicles into the game, and I just now came across an issue. Some of the added cars lost all their audio. Not only sirens and horns, but engine noise, tire squeal etc. As I said, only about a third of the added cars are doing this. I've installed all files into their correct locations (i am using mpchristmas2) and they load properly etc. For example, when adding bx's '14 impala, I replaced the vehicle files, carvariations, and vehicles.meta files correctly, and the car loads correctly, however I have no vehicle audio.
Just wondering what the solution (or if there is one) to this issue is. I am relatively new to the modding world so any help is highly appreciated.
Many many thanks,
Max
