Hi,

 

I want to increase the distance of the AI contrails.

 

I know it takes work on this file:

 

contrail = fsfx_PFX_3263496B6372304972726C58476F30724A6E6642493438546C5369687130724B //FSFX_PFX_Effect

 

under EFFECTS we have : 

fsfx_PFX_3263496B6372304972726C58476F30724A6E6642493438546C5369687130724B.fx

 

It can be opened with Notepad

 

Under which section should I change?

 

[Particle.0]

Lifetime = 2.00, 20.00

 

Lifetime=360.0, 360.0  <-------- These are numbers in seconds, I like 360 seconds (50 miles in a fast moving jet) but you  may like a lower number. Just remember that this simply alters how long the contrail                                        effect lasts. example: if I wanted a minute I would put the value of 60.0

 

I wish such a display up to 50 NM : http://contrailscience.com/wp-content/uploads/contrails.jpg

thank you for your support.

Hi Gilles,

 

[Particle.1]

Lifetime=1.00, 60.00

 

I suggest modifying the green part and leaving the red part to 1

 

Note that we aren't supporting modified installs of PrecipitFX. Editing effect files may lead to serious performance issues.

Thank you for your message,

 

Indeed, changing this value, the contrail is longer.

 

however, impossible to make it appear as AI aircraft is not visible, or at a distance.

The contrail is visible only when visible flypast AI. (circle of 10 Nm)

 

I wanted to reproduce the same effects as these pictures : 

 

 

there must be another value to change : (radius ?)

The effect is active if AI aircraft is in an area of less than 10 nm

 

I know that for light (beacon, strobe) aircraft AI, the distance is greater than 10 NM.

 

I am aware that such a request will have a very bad impact on game performance. (FPS)

We currently use the built-in technique that does not allow for effects to be displayed beyond this point.
