Unreal Niagara Skill

Niagara visual effects system for Unreal Engine.

Overview

This skill provides capabilities for creating visual effects using Unreal's Niagara system, including particle simulations, GPU particles, and procedural effects.

Capabilities

Particle Systems

• Create emitter modules
• Configure spawn, update, render
• Handle particle attributes
• Implement GPU simulation

Module Development

• Create custom modules
• Implement scratch pad modules
• Handle data interfaces
• Build reusable libraries

Integration

• Spawn from Blueprints/C++
• Handle events and triggers
• Integrate with gameplay
• Manage performance

Advanced Features

• Implement mesh particles
• Create ribbon effects
• Handle simulation stages
• Build fluid simulations

Prerequisites

• Unreal Engine 5.0+
• Niagara plugin enabled

Usage Patterns

Spawning Effects

// C++ spawn
UNiagaraComponent* NiagaraComp = UNiagaraFunctionLibrary::SpawnSystemAtLocation(
    GetWorld(),
    ExplosionEffect,
    Location,
    Rotation
);

// Set parameters
NiagaraComp->SetVariableFloat(FName("Scale"), 2.0f);

Blueprint Integration

1. Add Niagara Component
2. Set Niagara System Asset
3. Call Activate/Deactivate
4. Set User Parameters
5. Handle completion events

Best Practices

1. Use GPU simulation for large counts
2. Create module libraries
3. Profile with Niagara debugger
4. Set scalability settings
5. Use LOD for distant effects
