A selection of my modded cars come with modified sound files. It used to be that they made sounds without any extra mods, but this seems no longer the case. Does anybody know if there is a mod I need or some editing I need to do to make the sounds work? This problem is for the following cars: Renault 5 Turbo, DSC Scarab, and BMW E30 M3 1987.
Like any modding during the development phase, things are bound to be broken due to changes in the game. it's something you're just going to have to live with. short term, try deleting the custom sounds and see if the defaults work with those cars?
