Smoke at start up

Hey Guys when the aircraft starts up and there is those puffs of smoke, it is not lined up correctly with the exaust ports is there a way to fix this problem and where in the aircraft cfg would I look for it thanks
 
Look into DC's P-38 aircraft.cfg and you will see how to do it. The engine and prop locations are separated. The startup smoke is based on the engine location.
 
Hi Phantom,

The smoke effect is defined in the [EFFECTS] section of the aircraft config:

[effects]
wake = fx_wake
dirt = fx_tchdrt
concrete = fx_sparks
touchdown = fx_tchdwn_s, 1
startup=fx_Beaver2Start
contrail=fx_Beaver2Smoke

My guess is that the position of the startup effect is defined by the position of the engine:

[GeneralEngineData]
//0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
engine_type = 0
engine.0 = 6.6, 0, 0,
fuel_flow_scalar = 1.05
min_throttle_limit=0.0
max_contrail_temperature=5

I don't think changing the engine location is a good idea so I suspect that you need to edit the fx file to change the start position of the effect.

[Emitter.0]
Lifetime=7.25, 8.00
Delay=0.00, 0.00
Bounce=0.12
Rate=35.00, 45.00
X Emitter Velocity=0.00, 0.00
Y Emitter Velocity=0.00, 0.00
Z Emitter Velocity=0.00, 0.00
Drag=0.00, 0.00
X Particle Velocity=-0.25, 0.25
Y Particle Velocity=-0.25, 0.25
Z Particle Velocity=-8.00, -6.00
//X Offset=0.0, 0.0
Y Offset=-0.75, -0.75
Z Offset=-3.00, -3.00

Pitch=0.00, 0.0
Bank=0.00, 0.00
Heading=0.00, 0.00


This is just my guess work - seems logical. But I could be wrong.

All the best

I think the default jets do have a small puff of smoke on startup, but a little too far forward if I remember. (Position is based on the engine position in the aircraft.cfg.) Just about every jet I see start has a puff on startup as the little bit of residual oil in the tailpipe is burned off. Engines with worn bearings leak a little more into the pipe, and therefore have a bigger smoke cloud on startup.
 
The WOP bomber package has a jet startup effect for the Arado Ar 234.
It's named "fx_WOP_engstrt-234". I use it on all 1940s & 50's jets, looks good.
