Hi, I’m new here (probably the first time you’re reading an introduction like this ),
I’m starting to dive deeper into VFX a little bit and wanted to tackle Audio Visualization (specifically music) with UE4’s niagara system, since it seems to have a lot of potential.
I’m using a simple setup: A grid of cubes that should scale along the Z-axis when the Blueprint handeling the sound visualisation tells them to. The blueprint sends data to niagara using a “niagara parameter collection”. That works fine. The only problem I’ve run into is distributing the signals from the sound visualisation to the corresponding indizes on the niagara particle cubes. I hope you get, what I mean. I want my cubes to be distributed equally along the 20 frequency spectrums I’ve set in the blueprint. But I can’t seem to get anything sensible with the Particle ID and the passed index from the blueprint.

Shoutout to @cannabis.cod3r for his awesome tutorials that helped get me started in niagara in the first place. Thanks, man!
