With [[Flightgear]]'s increasing capabilities, '''bullet effects''' such as tracers and smoke on impact are now supported. You will need [[FlightGear 1.9.0|FlightGear version 1.9]] or later, in order to use the effects. | With [[Flightgear]]'s increasing capabilities, '''bullet effects''' such as tracers and smoke on impact are now supported.
