Lightning produces, on every detected beat, one or more jagged lightning bolts that strike from the edges of the canvas toward the centre. Each bolt branches randomly, fades out over a short lifetime, and adds an unmistakable feeling of high-stakes drama to the frame.
The scene is built around the percussive transient — the moment of impact. For metal kicks, rock snares, EDM drops, cinematic stings and trailer music hits, Lightning makes every beat readable visually.
Configure bolts-per-beat (1 to 7), branch probability, jitter amount, bolt thickness, glow, and lifetime. Higher branching probability gives a chaotic forking pattern; lower gives single dramatic streaks.
Pair with the Bloodstream or Cyberpunk City palette and the scene reads as cinematic violence — perfect for action-trailer-style music videos.
