• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Hi there

I searched the whole Effects- Threads for a question but i didn't became more intelligent about my problem :)

I use fsx and i am triying to extend the smoke effects, when engine is on fire (for example at boeing 737-800).

You see in the picture below, the range of the smoke is not really long and seems to be cut at the end. i would like to make it longer, so... any idea how?

Thank you very much, regards Daniel.

This is usually done by extending the life of a particle. Paste the code for the effect and I'll show you how to extend it.

Thanks for reply Misho!

Unfortunaletly, i am not quite sure about what document you need (that's what my problem is actually).

When i open the aircraft.cfg there is in the boddom a ligne, called Smokesystem.

[SMOKESYSTEM]
smoke.0= -15.0, -16.3, -3.8, fx_smoke_ffx3
smoke.1= -15.0, 16.3, -3.8, fx_smoke_ffx3

So i opened the document fx_smoke_ffx3 and i found that:

[Library Effect]
Lifetime=5
Version=1.00

[Emitter.0]
Lifetime=0.00, 0.00
Delay=0.00, 0.00
Bounce=0.00
Rate=44.00, 66.00
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=0.00, 0.00
Y Particle Velocity=0.00, 0.00
Z Particle Velocity=0.00, 0.00
X Rotation=0.00, 0.00
Y Rotation=0.00, 0.00
Z Rotation=0.00, 0.00
X Offset=0.00, 0.00
Y Offset=0.00, 0.00
Z Offset=0.00, 0.00

[Particle.0]
Lifetime=0.50, 1.00

X Scale=0.80, 1.50
Y Scale=0.80, 1.50
Z Scale=1.30, 1.80
X Scale Rate=0.50, 1.00
Y Scale Rate=0.50, 1.00
Z Scale Rate=0.10, 0.20

Z Offset=0.00, 0.00
Fade In=0.00, 0.00
Fade Out=0.55, 0.57

Face=1, 1, 1

[ParticleAttributes.0]
Blend Mode=1
Texture=fx_1.bmp
Bounce=0.00
Color Start=55, 55, 55, 15
Color End=100, 100, 100, 5
Jitter Distance=0.00
Jitter Time=1.00
TempK=107.00
TempRate=0.01
uv1=0.50, 0.75
uv2=0.75, 1.00
X Scale Goal=1.50
Y Scale Goal=1.50
Z Scale Goal=1.50
Extrude Length=3.00
Extrude Pitch Max=0.00
Extrude Heading Max=0.00

BUT, i guess that document is only for the smokesystem i can activate by keybord-button Q and not the smoke for an enginge failure, isn't it?
 
Yes - I think the file you need to mod is called fx_engFire.fx. You DO understand this will mod ALL the engine fire smoke trails within FSX? It is an univesal effect, not unique to any particualr AC.

Anyway, in fx_engFire.fx, find the section that starts with:

[Particle.0]
Lifetime=2.00, 5.00
Type=19

and change Lifetime values by adding, say, 5 to each. This will effectively double the trail length:

Lifetime=7.00, 10.00

Do this for every Particle. For Particle.1, add scaled values: 0.7 and 1.05.

You WILL observe performance (FPS) drop - that's why default trails are short. BTW - the two values are min and max of the random value chosen by the system... so every time particle is "born", it may have any lifetime value between 7 and 10 seconds, after which it will be "killed off".

Moah, you clever one! I guess this will help me!!

One question left, are you sure it is fx_engFire.fx and not fx_engsmoke.fx and fx_engsmoke2.fx ?

Thank you :D
 
I am NOT sure :p - that's for you to establish and play with. Shouldn't be too hard to figure out... Easiest thing is to remove the FX file from the directory. When you stop getting the effect - that's your file :cool:

Misho
 
Gaawd, what a good idea!!!
I'll do this :D

I'll answer againt, when it's done :D

Edit:
Well, it is done! :) But actually, 7.00 and 10.00 weren't enough, it didn't double the length :(
I tried a bit, then i changed the counts to 32.00/35.00 (and 3.20/3.55) and finally i saw a difference (picture beneath)!
By now, the fire himself is a bit longer aswell. I guess the part 3.2/3.55 is for the fire only and the other particels are for the smoke. So i guess it would look nice to use 32/35 for smoke parts and something around 1.2/1.55 for fire part.
For the framerate: I still get my 30FPS ;)

Well, there you go! As I said, it needs a bit of experimenting. Good show!

Misho
 
Thanks ;)
Yes experimenting is everything! :)

But without your indication i wouldn't have found the right document and settings. So thanks again.
