Unreal 5.2 September Update! Readme

*** I recommend opening the Map_NiagaraFlockExample level to see how these Blueprints are used. Thanks! ***

This pack features 5 Butterfly meshes, with highly customizable material animation and other parameters – including color customization, low poly shading, and fresnel highlights. Easily create new variations by changing material instance parameters.

The new flocking blueprint systems allowing you to quickly add butterfly flocks to your level with different behavior and functionality. Flight behavior is determined by the InitialFlightType enum variable. Some examples include:

Perch: Butterflies fly to nearby Perch actor locations. (Perches are detected by the collision component, so no reference variable needs to be set.)
Free roam – Fish remain idle until approached, and swim only to avoid Players/intruders.
SplinePath: Butterflies flocking along a path (make sure to set the PathActor reference variable to a nearby Path BP)
FlockingPoint: Butterflies flocking randomly within a box. (You can set a BoundaryBox Actor or use a Flight Path BP.)
Follow Intruder – Fish swim toward the nearest intruder.

The Niagara system has modules for flocking, raytraced collision detection, spline flightpaths, random idling, and more!

Static Mesh Animations: All animations are made with material WorldPositionOffset, offering lightweight performance, extra control over animation speed/rotation values and other parameters. Works with any custom mesh that is properly oriented along X+ axis – wing geometry must be marked with Green Vertex Color (Value > 0)
