Niagara audio works in the editor but not the build

Unreal Engine
1

I’m currently working on a project that uses FMOD and UE4.

I setup some events to work with Niagara particles and they play just fine in the editor.

The strange thing is that when the project gets built, they don’t work anymore

The particles themselves are visible but no sound can be heard.

Hi,

Are you using Play FMODEvent or Play Persistent FMODEvent?

There is a known issue with Unreal Engine 4 Play FMODEvent, substituting Play Persistent FMODEvent should solve the issue. Or if it is possible updating to Unreal Engine 5.

Hey, thanks for this. Unfortunately this didn’t work either. I have a workaround that doesn’t use the Niagara system but if there are any alternatives do let me know.

Upgrading to UE5 isn’t an option at the moment.

Thank you,

Can you share any error logs when using the Play Persistent FMODEvent? What version of the integration are you using? Unfortunately, we are unaware of any other workarounds at the moment.

I’m not sure if the engine is throwing up any errors but I’ll take a look and see what I can find.
