Simple sound replacement so it sounds like you are driving on dirt/gravel instead of the annoying asphalt screeching. Just merge the art folder in the main directory and it will replace the sounds. If by chance you don't like it, do the same thing with the default backup file and it will restore to default. -edits- There can only be 1 collision sound at the moment, so either everything sounds like dirt, or everything sounds like asphalt. The main directory is usually C:\Users\(name)\AppData\Local\BeamNG\BeamNG.drive-0.3
It seems to change the sounds for all surfaces, not just gravel/dirt. Is this intentional? They sound much better than the crap tyre squeal in the game, but id still prefer to have it on tarmac. I may end up keeping them regardless, as i cant stand the standard tyre squeal.
They have the same name but are different files. If you change the name the game won't accept it. Yeah, since there are no different collision types right now every surface in the game is considered asphalt. I don't know nearly enough about the torque engine to make that kind of thing happen, but beamng will do it eventually.
