Rocket exhaust expansion effect (particles)

Recommended Posts

Hello folks,

Is there a way, to somehow force the particles to move like in the picture I drew?

not completely from the beginning of the simulation but after a certain frame?? :)

I would really like to re-create a rocket exhaust effect, when the rocket climbs higher into the atmosphere, then the flame goes outwards because of the thiner atmosphere.. 
(for example, the Photo below - my reference picture..)

I already have the expanding animation done.. I just need now to somehow force the particles to move behind my main simulation.. is this somehow possible to do?

I would really appreciate some help! :)

You could try attaching a line pointing down to the center of the emission area. Use the end of the line as a goal position for particles to seek. The length of the line determines the distance the particles travel before they are close enough to seek the goal.

Oh wow thank you... 

But I have already a curve (straight line) there, where I am animating the expansion of the flame.. and I don't want to destroy it lol.

so it should be seamless visible if its somehow possible

Or is it possible to make a certain amount of lines or curves with the shape I want, and then just animate them?

So that in the beginning of the simulation these lines will be as one line... and after some time then will expand, so that it will create an illusion that its one simulation of the flame... hope you understand me :D
