Keep particles inside an volume

Recommended Posts

Hi guys,


I've started learning particles and I now these particles beautifully advected by a curl noise. I like that it stays kinda within the same source shape by the curl noise.


But when I want to prevent the particles from flocking together with a POP interact node, they move away from each other, but also move outside the shape..


So I tried to keep them inside the (peaked) shape with POP Attract and Field Force, but that didn't really work. And then I found this old odforce post talking about using sdf for that, but the example hips were too old to see what's going on.

So I was hoping maybe someone could enlighten me on how this SDF trick is done, or maybe any other for directing particles with geo. :) If you want, you can take a look at the hip: 



Thanks in advance!
