Descrizione

EasyCrowds is deeply optimized based on Niagara GPU particle system and neighbor grid technology. It offloads animation rendering overhead to the GPU via Vertex Animation Texture (VAT), enabling simultaneous rendering of a large number of units without performance lag. Meanwhile, it leverages Niagara's flexible Scratch Pad Module for core logic coding, and cooperates with Blueprints to easily implement various complex behavioral interaction logics.
