In this Unreal Engine 5.4 Niagara tutorial, learn how to assign different initial rotation and position offset values to individual particles and meshes within a single emitter! We’ll cover using Execution Index, curves for precise per-particle control, aligning particles along shapes, and handling multiple meshes with custom mesh indices.
