Unreal Niagara VFX

Build and control real-time visual effects in UE5 with Niagara: understand the System/Emitter/Module hierarchy, expose parameters you can drive from gameplay, and spawn effects at runtime. Targets UE 5.4+. (Niagara replaces the legacy Cascade system.)

When to use

• Use when creating a Niagara System (NS_) and Emitters (NE_), wiring modules in the spawn/update stages, exposing User parameters to gameplay, or spawning/driving an effect (impact, muzzle flash, fire, magic) from Blueprint or C++.
• Use when the project has Niagara NS_/NE_ assets or references UNiagaraComponent.

When not to use: material/shader authoring (the look of a surface, not particles) is a separate topic; shader-programming covers cross-engine shader concepts. Audio for the effect → audio-design.
