Introduction and Features ​

Accurate propagation and obstruction of sounds within games is vital for both gameplay and player immersion. SweejTech Propagation is an innovative solution that utilizes GPU ray tracing to implement a robust and efficient audio obstruction system.

  • Natural obstruction results via highly performant GPU-Based system
  • Customizable project level control over obstruction
  • Customizable obstruction settings on a sound asset level
  • Set ranges for obstruction effects to mitigate minor obstructions or emphasize obstruction
  • Scale obstruction effects linearly or via curves
  • Per asset customizable timing for applying obstruction effects
  • Edit one shared reference asset to update settings across multiple assets
  • Dynamic adjustment of source spheres for overlapping geometry via the 'squishy sound sphere'!
  • Per actor or per component inclusion / exclusion from obstruction system (including geometry)
  • CPU Ray tracing fallback for lower end platforms and for models unloaded at large distances
  • Compatible with other Middleware!
