Does anybody have a tutorial on how to convert cars with 3d max
?

I decided to make a sound mod to muscle_car_2_us_v8 and in OpenIV everything seems ok but when i launched the game and spawned the car which uses this sound file (the Dominator) it did some weird sounds when revving/driving and idk how to fix this.

This is the mod ( just replace it in /x64/audio/sfx/STREAMED_VEHICLES_GRANULAR.rpf )
