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


This pack features 11 unique bird meshes and 21 color variants with highly customizable material animation and color parameters - including color masks, low poly shading, and fresnel highlights. Easily create material instances for more variations! Each mesh has 2 LODs: LOD0 is around 2.1k triangles, LOD1 is around 1.2k.


** Mesh can be change directly in the Actor. A separate LOD1 meshes is included for situations where you'd like less detail + better optimization for your scene.


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


  • Perch: Birds 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: Birds flocking along a path (make sure to set the PathActor reference variable to a nearby Path BP)
  • FlockingPoint: Birds flocking randomly within a box. (You can set up a BoundaryBox tool BP 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 use material WorldPositionOffset, offering lightweight performance and extra control over all animation parameters. Works with any custom mesh that is properly oriented along X+ axis.
