Very realistic looking fish behavior based on simple variables and tracers, a simple and beautiful solution to most simple, realistic underwater environments.

This system is about fish behavior, reproduction through automatic spawning copies with random sizes and behaviors preseted in species settings, population control at locations according to the basic settings, or for each specific location. Includes three types of fish to demonstrate the system. One of them, sprat, is with generation in particles for a lower load for system. And can be used to generate large crowds when needed.

Video demonstration how it looks on my own project - https://youtu.be/tw5zSm4N4y8

Of course, parts of my project, like everything except the fish and their behavior, are not included in this asset.

Attention! Demo scene starts on 30FPS limit. You can disable this limit by binding button “3”. To enable-disable VSync, bind button “2”. Showing FPS stats toggles by “1” button. All those options is just for demo, configured in Event Graph in “./Demo/ThirdPersonBP/Blueprints/ThirdPersonCharacter”.


Features:

  • Niagara particles used to emulate large fish crowds
  • Tracer based movements enables unique and unpredictable behavior
  • 3 fish meshes included for quick start and understanding the system
