I saw the particle tutorial series from zak, i understand so far particles and how to manipulate them.
But when it comes to a jet engine/spaceship engine, im pretty clueless how to create such a effect…
any ideas/suggestions?
Could you give us an example?
( Luos's Particle Showcase - Game Development - Unreal Engine Forums )
This is what i´ve done so far.
The problem is, i want the actual engine throttle to come out and the smoke more behind it.
If you look at this picture its exactly what i want:
But i have no idea, how i could shape an alpha texture like this in the particle editor from ue. Somehow i need to change the initial size in the beginning, than put it up in the middle and at the end make it very thin… but no clue how to do that and the tutorials dont talk really about this…
There are multiple ways to achieve that effect.
You could (like how i did the particles in that showcase) use a mesh and on each spawn change the size a little bit.
or in photoshop create a mask for that particular shape.
https://docs.unrealengine.com/latest/INT/Engine/Rendering/ParticleSystems/Reference/index.html < this does show all the things currently possible with Cascade.
For you in particular the Accelerator, lifetime, rotation(rate), size and velocity nodes should be of interest.
Also https://www.youtube.com/playlist?list=PLuqNhfvpWXRiHIFsstRqF_nDUzNyKVJLq if you want to know more about mesh based particles.
If I have some more time today I will make a working example.
(but its always best to try yourself 
)
Hey lous! Thanks for your answer!
I´ve readed the whole particyle system tutorials, watched all videos and im also a big fan of exploring things by myself.
I wouldn´t say my actual particle system is bad, i came already very far imo for the fact that i never did any particle systems… but it isn´t exactly what i wanted.
but i just don´t get the idea how to create such a shape.
I think i´ll understand this whole thing maybe even better if i see how you´ve created it… best greetings!
It shows how to make a mesh based thruster effect, and the readme of that yt page also contains a link to the project files and starter files.
Hope it helps
