Overview

Fracture Effects on a Destructible Actor allow content creators to set a specific sound (or sound cue) and a particle effect to fire off upon a chunk of the destructible breaking. These are set per depth layer, meaning the largest breaks can have a really potent effect and sound, with the smaller chunks getting less impressive sounds and effects.

Particles

This will spawn a particle system at each unique break event at a world position that averages the positions of the breaking chunks. So a single effect can be fired off many times on a strong destructible. However, if you turn support off, only one effect will fire, and will occur at an average location of all chunks in the Destructible Actor.

Remember, when adding a particle system to a Destructible Actor, make sure that particle system is a burst system with no (or very limited) looping, otherwise, you will end up with static particle effects in the area where the destructible broke.

Sound

This will fire off a sound or Sound Cue from the location of the breaking chunk. Again, as with the particle systems fired off on breaking, these are set per depth layer.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
