I'm new to expression. And I've been working on a thesis project which needs a little bit of expression knowledge. Basically I want to create a volume of balls moving in a shape while each has their own random motion. So I have the particles emitted from a volume mesh and goal to it. I use .goalU=.parentU/.goalV=.parentV to distribute the particles within the volume. I deform/animate the mesh and hide the mesh to have the particles move in the way I want. Now, I need to find a way to make the particles each has some motion within their own space instead of just stick as where they were born. I searched for lots of posts but still cannot find the right one. I tried to use gauss function but it doesn't add to much randomness and looks jittery. I also try to write some expression with goalU, goalPP, goalOffset... but I was not able to make it look right.
I will REALLY REALLY appreciate it if anyone can help me with it. THANK YOU!
