Blueprint_Effect_Fire - the FireAudio is audible even when P_Fire is hidden

[Tombolo106]

I’m using UE5.4.2.

I’ve added the Blueprint_Effect_Fire from the StarterContent Blueprints to a static mesh actor.

In the Blueprint_Effect_Fire’s details for P_Fire I’ve ticked Hidden in Game, so there’s no fire when the game starts. When the actor is hit in the game I use an EventHit to unset SetHidden in Game for P_Fire, and the fire appears.

This part is working OK - there’s no fire when the game starts and the fire appears when the actor is hit.

However, when the game starts, the fire’s audio is playing even though there’s no visible fire. I expected it to be hidden with P_Fire but it’s not, and I can’t find anything like a SetSilent for audio.

Am I doing something wrong or is it a bug?

I’ve realized that as well as using HiddenInGame, I need to also turn off AutoActivate for both P_Fire and FireAudio, and then activate both on the hit.
