Hi all,

I am trying to create a Fish bait ball like in the video  Fish-Baitball-ref.mp4. The shape is constantly changing as the fishes flock over them.

I created a shape,used a pointvop to deform it and then used a point deform to get the deforming points.

I am clueless as how to proceed further. I want the points to flock across the deforming shape.

Can anyone guide me to get this result? Thanks in advance.

Lots of ways.

You could use a pop flock which is a basic boids system.

Or the crowd forces nodes.

Or write your own setups with pop wrangles.

Or advect with a pyro solver.

Or use grains to deal with the particle separation.

Or try and fake it totally in sops with points moving on curves generated by curlnoise.

Or, or or or….
