Description


The Fish Spline System is a Blueprint which allows you to quickly and easily animate hundreds of creatures with ease. It has a low impact on performance using instanced vertex animated meshes that dynamically move along procedurally generated splines.


Video Example: https://youtu.be/T92ax6vkOMI


Each instance will have its own spline procedurally generated from one main control spline. These generated splines will have a random offset for each point, and an offset from the origin; all based on the value of your choice.


Choose how many fish you want, their Scale & Scale variation with ease. Set their starting position along the spline with the 'Distance' variable, and choose the distance between each instance. When working with hundreds of fish, you can simply check the "Spline Edit Mode" checkbox to hide all additional splines.


You can also easily replace the mesh and materials.

Automatically grab the meshes default materials, or use the 'Custom Materials' checkbox to pick your own.

Set the Desaturation, Hue shift & Random Hue Shift of each blueprint instance in order to distinguish each school.


With the 'Dynamic Speed' checkbox enabled, the fish will alternate between slow and fast speeds based on timers with random variables.

  • Choose how long you want your fish to swim slow and fast for.
  • Choose the speed at which they accelerate and decelerate
  • Choose the movement speeds, Animation Speeds, and Animation intensity


With an abundance of customizable settings, the Fish School System is perfect for realistic flock animation!
