Hello Developers i have a question how to make a (Particle Effect,Blueprint)for Helicopter Land and Lift up that will effect the ground with Dust and grass Swinging round of Heli.
Like this
hello and welcome 
I’d use a combination of the following:
- Area particle effect with dust,
grass,mild air distortion etc…
activated when the helicopter is
within a certain distance of the
ground… done right, very low
performance cost - Wind effect actor combined with foliage specifically set up to
respond to wind actors… medium
performance cost - Maybe even a force actor, to push against objects, AI and players in the
immediate vicinity of the landing… low performance cost
You can find tutorials on how to set up all of these… 2 & 3 are fairly straightforward to set up, 1 will take a moderate amount of skill with particle FX to look right
