Hi all, i have noticed that quite a lot of you get contrails from the wings in your shots, and i was wondering how you do it?  Because i never seem to see them in my sim

Thank you, ill give it a try

Most of the IFDG aircraft have the tip vortecies.... they work off the I (smoke) button so if you are adding them to an airliner the CFG from one of the IFDG aircraft would be the place to start.

It would indeed, but for wingtip contrails I'd use something different to the smoke effect (because that's the default Extra 300 smoke, right ???)
Take a peek in an iFDG Airbus' CFG or a POSKY's CFG (if you have any of their aircraft), see what effect file they use and implement it into your CFG entry like so:

smoke.0=0.00, -0.70, 1.40, fx_poskysmoke_w (the filename of the effect file is a random, made up one, so it isn't a file )

Do you know what the three numbers (0.00, -0.70, 1.40) mean or do you know how to edit these to get your effect where you want it?

Each number represents a distance from the aircraft's centre point (which is 0.00, 0.00, 0.00). Each number governs a different factor, these being height, distance forward.backward and left/right of the centre point, e.g:

smoke.0=0.00, -0.70, 1.40, fx_smoke_w
                 ^        ^       ^
                 1         2       3

1 = The height from the centre point. (A positive number is how high the effect is, a negative number is how low the effect is.)

2 = The distance forward / back from the centre point. (A positive numer is how far forward the effect is, a negative is how far back.)

3 = The distance left / right from the centre point. (A positive number is how far left [....I think ] the effect is, and negative is how far right.

Hope this helps you 8)

Ive had a try at this, and does anybody know how to get the smoke thinner

eno....

i don't have any ifdg aircraft, could you give me a glimpse at the .cfg

Contrails come out above 29,000ft or depending upon the temperature
