# 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 ```cpp // 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 ## References - [...
