In header:
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Music)
class UAudioComponent* destroyedAudio;
In the editor (after rebuild and relaunch):
You can see that it doesnt appear under “Variables” but is accessible on the graph
Hi,
Have you double checked that your filter hasn’t been reset. If you click on the little eye icon ensure “Show Inherited Variables” is checked.
It sometimes gets unchecked. Even if its checked, uncheck and recheck it. =)
Hopefully that helps =)
It was unchecked , I checked it , still no Music category 
Should do VisibleAnywhere instead of EditAnywhere
