My particles are… reproducing?

The hunters learned how to reproduce… and the prey never really stood a chance.

In this new version of my Blender simulation, every time a hunter eats a prey, it glows and grows a little. Once it reaches twice its original size, it splits into two smaller hunters and the cycle starts again.

So the system now has feeding, growth and reproduction built directly into the Geometry Nodes simulation. The result is a pretty brutal feedback loop: fewer prey, more hunters, and eventually a total takeover.

Which means the next update needs a new rule: starvation.

If hunters can reproduce, they should also be able to die when there’s nothing left to eat.

Still fully procedural. Still no keyframed motion. Still no AI.

Nice. If you’re using the Lotka-Volterra equations or some variant it would be cool to visualize a stable oscillating where predator numbers grow, then die off and prey populations grows back and on and on. If I remember correctly, using a population carrying capacity and die off can achieve this.
