Error: Selected Child Not Available

Question

I am trying to trigger an event for our character's attack. The event plays a sequenced whoosh followed by an impact set inside of a switch container. I have tried triggering the event from both the animation and from a post event on the blueprint for  the character itself.

I have followed the steps listed in the documentation. I ensured that the switch group had a default switch, was loaded into the soundbank, and generated the soundbank again in unreal. I still can not seem to trigger this event properly. I will attach some pictures. Any help is much appreciated.

Answer 1

This ended up being an error with how my event was structured. I was trying to play a single sequence container which had a random container followed by a switch container inside.

The fix was editing the event to call both the random and the switch containers one after the other from the event layout. 

Answer 2

Sometimes same issue happens when the free licence project reaches a limit of 200 sounds.

So deleting some unimportant events will help.
