I made a class that fades into the next song by calling AudioComponent.FadeOut(), changing AudioComponent.SoundCue, and then calling AudioComponent.FadeIn(). I’m 99% sure there’s no way to just do a direct crossfade of playing both SoundCues at the same time using just one AudioComponent. You’re already doing it the best way possible using just UScript. I think if you want a fancier solution, you’ll have to use Wwise or something similar.
