Hello,
Something like this could help you for particles movements.

Create a vector flow then use it as a force for your particles via
closest location.
Hope it can help you!

Hi guys, just came across this task where basically I need to create a
kind of growing particles effect (Ex: foam/bubbles) where the
particles move, multiply and grow on a deforming surface.
Basically, cant use stick to surface, flow around surface also doesnt
work since the particles need to kind of stay on the surface at all
times. Cant get Slide on surface to work properly too.
Using an expanding weight-map kind of gets something close but quite
different to what i wish to achieve, the problem is that the particles
should also move and slide, so they cant be stuck on the surface,
but follow its deformation..
I also tried a process using states to make the particles spawn once
they achieve a certain size, pop into 2 or 3 smaller bubbles which in
turn pop again into smaller ones, but couldn't get them to follow the
surface properly.
I guess that might be several approaches for the issue, maybe someone
knows a compound that does something similar that could maybe be
adapted to this purpose.
Cheers
