I have uninstalled reinstalled cleared catche multiple times but for some reason every time I spawn in one of your d-series when I use a mod that has interior sound it bleed through after like 10 seconds, this mostly applies to mods that add onto the d-series but I have had it happen when I use the md-series. But would it not be a good idea to make a sound difference between the outside and inside because not saying loud is bad but the engines are very loud and It would be better (in my opinion) to have that because I don't think I am the only one who would want this, ofc for the cars that don't have a sound difference. edit: OMG IM DUMB I never specified its when you make the d-series you made a traffic car im so sorry I wasn't thinking straight so test this by making one of you're various d-series configs a TRAFFIC CAR then spawn in an md-series or something then drive around in first person until you here the outside bleed in
Update I have fixed this problem but after it developed a new problem with it takes alot of resources to spawn in one of the ceep d series trucks and its so bad it actually makes the game hiccup every time a new one spawns in when I set them as traffic cars ( this is not part of my performance settings idk why it does this) so if you could look into that problem it would be great
