Info On Sound Vizualizer

Do any Epic Devs know who programmed the Sound Visualizer? Is there a way to contact him/her either via email or PM? I’d like to poke his/her brain as to the math behind it and why certain functions were used to build it and not others.

While you’re at it, can you ask them to make it work in packaged builds? I went to a day’s worth of work getting it to drive an emissive texture’s brightness to the beat of a song, only to find out after all was done, that it doesn’t work in packaged builds and is therefore useless.
I would use Exi’s sound visualization plugin but it makes my 4.20.3 engine unable to compile so I might have to change to 4.19 if I want this feature.
