So me and a couple of my friends are working on a game in unreal and we want to have an audio visualizer in game. I’m completely new to FMOD and I only just figured out how to make looping music so the simpler the solution, the better :D. We’re using blueprints and we reeeeeally don’t want to use c++… Is there a way to do this with only blueprints?
