wake effect for sea planes you mean? or ships,
wake effect is not automatic like in FS2002
ships have wake as [extra] section in dp file
ships make wake when they sail across land or fly through the air
in fs2002 seaplanes as with all planes the ground contact effects are in the aircraft.cfg
as are lights effects
CFS2 doesnt implement ground contact effects like fs2k does, the puff of dust on landing is hard coded like the engine start up smoke, but it does implement a panel light effect when you hit the L key.
The wake effect can attached as a light in the aircraft.cfg and can be manualy switched;
check out the stock F4U1A aircraft.cfg to see how
[LIGHTS]
panel=0.00, 0.45, -2.00, fx_vclight
the numbers are the x,z,y coordinates for the origin of the effect, as meters? from the centre of the plane,
in this case it is fx_vclight that is called but any effect can be attached and switched in this way.
caution though, some effects cause damage, I attached an explosion to a destroyer to simulate depthcharge attacks.
effects can also be triggered by gauges
I think there is a gauge for seaplane wake but I have never used it.
