The Procedural Instance Spawner is made to enrich game environments through procedural spawning.

The spawner utilizes background threads to minimize performance impact and is fully deterministic.

Includes blueprint functions for removal of spawned meshes in runtime.

Version 1.3 - Bug fixes and added setting for including objects with mobility set to Movable when tracing (Off by default).

Version 1.2 - Significant generation speedup!

(After updating to the new version, please regenerate the spawners to ensure optimal performance. This will prevent duplication of instances spawned with previous versions.)

Version 1.1 - Added support for filtering by Surface Types.



  • Runtime spawning
  • Utilizes background threads
  • Hierarchical synchronization enabling complex worlds
  • Support for Large World Coordinates
  • Accurate collision and proximity tests
  • Filter spawning by object types to spawn on, object types to spawn under and object types that blocks spawning
  • Center spawning around active camera, world location or a specified actor
  • Advanced settings for rotation, scaling and height offset of spawned instances
  • Settings for spawn filtering includes: Height interval, Slope intervals, Collision checks, Sphere traces, Object Proximity, Cluster filtering and filtering by Surface Type/Landscape Layer
  • Presets to immediately get going
  • Settings that allow for fine tweaking
  • Prepared for adding of custom spawn point filtering and/or function for finding spawn points
