Thanks for your reply, @Minus_Kelvin . That’s a ton of great info! I hope you don’t mind but I’m going to reiterate my first question because I feel like to maybe wasn’t being clear enough:
In a situation where I’d want to use a soundcue with a random node pointing to many different wav files, at runtime, when the wav is randomly selected by the soundcue, what would be the best way to determine what wav was selected so I can then select the correct associated NRT file to use to drive other blueprint data?
For instance, let’s say I have three explosions being selected buy a Random node and they are named thus:
BOOM_01
BOOM_02
BOOM_03
Let’s also say I have these associated NRT files:
BOOM_01_NRT
BOOM_02_NRT
BOOM_03_NRT
The sound cue is triggered, and BOOM_02 is played. Where can I grab that info so that I can also play BOOM_02_NRT with Synesthesia at the same time?
I hope this questions makes my conundrum more clear… I love the decoupling of the analysis files from the wav files–it’s a good choice
