I have created a particle effect that is influenced by a vortex. Now I want to create a plane that is the parent of both of these object. That way this plane controls the orientation of the emitter and the vortex. However, when the plane is rotated, I want the moving particles to stay oriented so that they are on the plane, as if they are "sticking" to it. The overall result should be a plane that has particles spinning in a vortex pattern. where u can rotate the plane and the particles will rotate along with it, giving the visual of a particle disk.

How do I make the particles orient with the plane at all times?

Collider

Add a cube and parent it to the plane that the particles should remain within.
1

Scale the cube so that it is very thin and large enough to encompasses the simulation area.
2

In the Physics Properties tab, add a Collision modifier and set Damping to 1 to keep the particles from bouncing inside too much.
3

If particles are leaking out, change the integration model or increase the simulation subframes.
4

Opposing Wind Forces

Create two equal Wind force fields like in the image below.
1

Set the Strength of both fields to a high value and make sure that there is some falloff.
2

As long as these two forces are equal and parented to a plane (or any object), all particles should stay pretty close to the plane between the two force fields.

    $\begingroup$ I had some issues with this method. I tried some simple rotation animation, and it would work fine until it stopped moving. Then it would go wonky as it balanced itself out. It would spread and wobble a bit. I like your idea but I'm not sure if it will work properly, as I do not want the particles to deform or wobble. $\endgroup$

  • $\begingroup$ I believe that stronger forces with sharper falloffs could reduce the wobbling, but I have another solution in the works ;) $\endgroup$

  • $\begingroup$ cool, hit me with it when u've finished! I'll keep that other idea in mind as well! $\endgroup$
