As far as I know, the Sound Meta system was created when it moved to Unreal Engine 5.
Then, will the existing Soundcue system disappear?
I’m writing here because I don’t have any information about this.
Hey @Hongbience! Welcome to the forums!
The Metasound system is best seen as an extension of Sound Cues to give those with more audio engineering abilities more control over sounds. As far as I’m aware, Sound Cues aren’t going anywhere, at least for a long, long time!
