Create and control VFX in Unreal Engine 5 with Niagara: systems and emitters, modules and the spawn/update stages, exposed User parameters, and spawning or driving effects from Blueprints or C++. Use when building particle effects, NS_/NE_ assets, spawning a Niagara system at runtime, setting User parameters, or when the user mentions Niagara, VFX, or a particle system in Unreal.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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`.

## Core workflow

1. **Understand the hierarchy.** A **Niagara System** (`NS_`) is the effect you place/spawn; it
   contains one or more **Emitters** (`NE_`, often emitter *templates*). Each emitter runs in
   stages: **Emitter Spawn/Update**, **Particle Spawn/Update**, optional **Event Handler**, and
   **Render**.

How to install

The exact contents, by fingerprint

mdr add ukanwat/overtime/unreal-niagara@sha256:39a0c0e390d7d272

The line at the top of this page pins the label git:20260812.5b73825, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
