I am a audio modifier for past Train Simulation games, and Train Sim World is a game using Unreal Engine. I have since downloaded Unreal engine, and several versions, but still am unable to figure out how to modify the sounds in this game. I have seen it done only once, it is still new to the community, and of course I have tried to read up on it, but I still don't know how to even get the game into Unreal, or for that matter, take a sound file, and modify it in Unreal, then, simply use the same file name, and replace it. I have certainly uncompressed the game file, so I have access to the .UASSET files, but still need assistance.. If there is anyone out there who might be able to help, excellent. I'd be willing to pay someone for their time.
