UGameplayStatics::ActivateReverbEffect
#include "Kismet/GameplayStatics.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Applies a Reverb Effect globally without requiring an Audio Volume in the level. Useful for scripted sequences or dynamically changing environments where placing a volume is impractical.
Caveats & Gotchas
- • TagName must be unique per activation; calling this again with the same tag replaces the previous activation rather than layering a second one.
- • When an Audio Volume and a manual reverb share the same priority, the Audio Volume takes precedence; raise Priority above 0 if you need the manual reverb to win.
