### Summary

The Progress Based Mesh device plays a sound on every progress step and when the progress target is reached. This sound cannot be removed or replaced:

- With Progression Type “Instant”, there are no audio fields available in the Details panel at all, yet the device still plays sounds.
- With Progression Type “Continuous Rate”, the audio fields (Progress Audio, Regress Audio, Finish Audio) are available, but they are ignored. Leaving them empty or assigning a custom Sound Cue makes no difference – the default sound is always played.

Devices

### Steps to Reproduce

1. Place a Progress Based Mesh device in the level.
2. In Visuals \> Threshold Mesh, use a single entry with a custom static mesh and leave Transition Sound Cue empty.
3. Set Progression Type to “Instant”.
4. Note that no audio fields are shown in the Details panel.
5. Trigger progress on the device (e.g. via a button or trigger) in a live edit session and let it reach its Progress Target.
6. Switch Progression Type to “Continuous Rate”.
7. In the Audio category, leave Progress Audio, Regress Audio and Finish Audio empty – or assign a custom Sound Cue.
8. Trigger progress again and let the device reach its Progress Target.

### Expected Result

- With “Instant”: no sound is played, or audio options are available to control/disable the sound.
- With “Continuous Rate”: no sound is played when the fields are empty, and the assigned custom Sound Cue is played when one is set.

### Observed Result

In both modes, the device always plays its built-in default sound on every progress step and a “filled” sound when the Progress Target is reached. The sound definitely comes from the Progress Based Mesh device itself, not from the triggering device.

### Platform(s)

PC

### Additional Notes

UEFN 6.0.0-59596594+++Fortnite+Release-43.00

- With Progression Type “Instant”, no audio fields are exposed in the Details panel, so there is no way to change or disable the sound in this mode.
- With “Continuous Rate”, assigning a custom Sound Cue is ignored as well – the default sound is still played.
- This suggests the Audio options are not being applied at all, and the device always falls back to its built-in default sounds.
- No Transition Sound Cue is assigned in the Threshold Mesh entry.
