Hi,

What is the best way to have the particles follow a path (and control!) the particles? Like in this commercial - https://www.youtube.com/watch?v=flro8QVDfn0 [youtube.com]
I guess they have used a wind pop or something to create the organic movements, but the path is somehow controlled.

POP Curve Force DOP is the way to go.

And to apply force around an axis use POP Axis Force.

Thanks!

It works very well, I ve added pop torque, pop spin drag and some wind forces.
What I would like to do is separate the particles a bit. As they follow the curve they are often “gathering” together on the curve, so I would like them to spread out more. Like setting a distance they need to keep from each other. Is that possible? Nor for all but for maybe 60& of the particles.

you can use POP Interact force to keep them separated
