Maaass Particle brings together Unreal Engine’s high‑performance Mass Entity system, Niagara’s flexible rendering pipeline, and Bone Animation Texture (BAT) technology to deliver real‑time, large‑scale crowd simulation and animation.
By streaming per‑entity data—location, velocity, orientation and animation state—into Niagara and baking skeletal animations into textures via BAT, you get smooth, GPU‑driven rendering without sacrificing any of Mass Entity’s built‑in behavior or scalability.
