Fish School System V1 UE4  

Download Packaged Demo

The Fish Spline System allows you to quickly and easily animate hundreds of fish with ease. It uses instanced vertex animated meshes that dynamically move along procedurally generated splines.

This System is compatible with an abundance of Fish Meshes, found in the Fish for School System V1 and Fish for School System V2 packages.

PLEASE NOTE: There is a newer School System available, which operates differently than this one.

Version 1 of the School System operates using splines, not particles.
It may have lesser performance than the School System V2, but can provide a more specified & controlled outcome due to it animating all the fish using splines. This may be more useful for certain scenarios. 

Please check out both packages before purchasing one or the other, or both!
Please CLICK HERE to view Version 2 that uses Niagara Particles!

With the 'Dynamic Speed' checkbox enabled, the fish will alternate between slow and fast speeds based on timers with random variables. Choose the number of fish, the Scale and Size variation. Set the starting position along the spline 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.

Important Note: Skeletal meshes aren't supported, but your animations can easily be converted to vertex animations using 3DS Max (See video description for tutorial).

NOTE: This package does not support Unreal 4.17 and 4.18 due to a bug in these engine versions.
