Niagara FX

VortexFX Actor

The VortexFX Actor generates Niagara particle systems along the vortex path.

Setup

  1. Place a VortexFX actor in your level
  2. Reference the VortexTunnel actor's spline
  3. Select your Niagara system
  4. Configure spacing and rotation parameters

Module Scripts

The plugin includes Niagara module scripts that:

  • Calculate spawn points along the spline
  • Orient particles to face vortex direction
  • Synchronize with vortex rotation
  • Handle particle velocity along the tunnel

Runtime FX Generation

Use the Pawn Movement Component to spawn FX at runtime:

  1. Attach the component to your pawn blueprint
  2. Configure FX spawn rate and lifetime
  3. FX will trail behind the pawn as it moves through the vortex

Optimization

  • Use LOD for distant particle systems
  • Limit particle count for performance
  • Cull systems outside camera view
  • Adjust spawn rate based on movement speed
