This is not effects package! It's a system that can be easily combined with any assets, your own or from Marketplace.

Setup effects for all collision events in your game - projectiles hitting different surfaces, thrown chairs, boxes or falling body - anything that generates Hit Event now will also spawn Particle, Sound and Decal.

Super easy to setup - just add the component to an actor, and that's it!

Full documentation, and movie clips to help you move around.

Technical Details


  • System that works, just by adding a single component to target actor!
  • Working with anything that generates Hit Event
  • Effect will attach to hit target, f.e. bullet hole in doors will move with opening - closing, and if Skeletal Mesh was hit - blood will stick to hit bone.
  • Being component - you don't have to create new Blueprint for each new actor, just add a component to an object on scene
  • Organized project files supports easy migration - all necessary assets are in one folder, the rest - mostly examples - can be deleted without any errors or dependencies.
  • Creating new setups is as easy as possible with only two steps:
  1. create new Data Table and fill up the rows
  2. select it in IES component
