Why wouldn’t that work? I’m confused. You can code the particle emitter to change dependent on different things. Transparency, enabled, spread, etc. You could also tween the attachment position/offset you place the particle emitter under in the hierarchy tree/object browser via a script.
If you mean “displacement” as in the wavey effect, like shown on the left of this image:
Then, that ‘wavey-ness’ is caused from the movement of the object(plane) itself. That’s what it seems like anyway- if the plane turns, then the particle attached will as well.
You may or may not be aware of these recourses:
It proves that you can program wind effects yourself, but it takes work/programming knowledge. Maybe that helps, maybe it doesn’t.
