Beefy Blackbirds (Niagara Bird System)适配UE4.27
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.
Technical Details
IMPORTANT: Grass, and water assets sold separately.

我建议打开 Map_NiagaraFlockExample 关卡来查看这些蓝图是如何使用的。谢谢！
此包包含 11 个独特的鸟类网格和 21 种颜色变体，具有高度可定制的材质动画和颜色参数 - 包括颜色蒙版、低多边形着色和菲涅尔高光。轻松创建材质实例以获得更多变化！每个网格都有 2 个 LOD：LOD0 大约有 2.1k 个三角形，LOD1 大约有 1.2k 个三角形。
** 网格可以直接在 Actor 中更改。包含单独的 LOD1 网格，适用于您希望更少细节 + 更好地优化场景的情况。
新的群鸟蓝图系统允许您快速将具有不同行为和功能的鸟群添加到您的关卡中。飞行行为由 InitialFlightType 枚举变量决定。一些示例包括：
Perch：鸟类飞到附近的 Perch 演员位置。 （碰撞组件会检测栖木，因此无需设置参考变量。）
自由漫游：鱼保持静止直至有人接近，并且只在避开玩家/入侵者时游动。
SplinePath：鸟群沿着路径成群（确保将 PathActor 参考变量设置为附近的 Path BP）
FlockingPoint：鸟群在框内随机成群。（您可以设置 BoundaryBox 工具 BP 或使用 Flight Path BP。）
跟随入侵者：鱼群向最近的入侵者游动。
Niagara 系统具有用于成群、光线追踪碰撞检测、样条线飞行路径、随机空闲等模块！
静态网格动画：所有动画都使用材质 WorldPositionOffset，提供轻量级性能和对所有动画参数的额外控制。适用于任何沿 X+ 轴正确定向的自定义网格。
