Engine sounds needs to be fixed. This is a problem especially if you're making a tank, truck, bus or any heavy duty vehicle, it sounds like driving a sedan or smth like electric vehicle. Or if u want your car to sound like the real engine, also pls add a selection of car engine sounds in the part settings of the car engine. Yeah you can pick any sounds you want like v8, v6, Cummins, tank, VVT, Motorcycle, sports, and bus engine sounds.
