Contrails

[stuart1044]

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

[cspyro21]

It's an effect that comes with some aircraft, an example I can think of is the DSB Tornado. When you pull a steep turn with your wings extended, wingtip contrails appear
If you wanted to add it to other aircraft, you could edit the aircraft.cfg and add the effect as a smokesystem to it - so when you pressed the "I" button, the contrails would appear

Thank you, ill give it a try

[cspyro21]

No problem, if you encounter a problem I can help

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.

What would the .cfg entry look like....

something like this perhaps...

[SMOKESYSTEM]
smoke.0=0.00, -0.70, 1.40, fx_smoke_w

smoke.0=0.00, -0.70, 1.40, fx_smoke_w

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?

[stuart1044]

I have no idea what they mean, not really up to scratch with anything in the .cfgs

[cspyro21]

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

Well im a bit busy tonight, doing uni work, as well as poping in here all the time, so ill give it a whirl possibly tomorrow and show the results.

Thanks for the help

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

You'll need a new effect instead of using fx_smoke_w. Let's take the DSB Tornado F3 for example, I've taken this entry directly out of its CFG:

[smokesystem]
smoke.0= -1.5, -15, -22, fx_dsb_tornado_contrail25
smoke.1= -1.5, -15, 22, fx_dsb_tornado_contrail25

The file is fx_dsb_tornado_contrail25, so if you have it (or want to download it), you could note the filename and create your own contrail effect on your own aircraft using the same file.

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