I have a wall of cubes which i want to light up so they look like an equalizer. So each cubes switches between a diffuse and emission shader in a pattern. Is there an easier way to do this than manually going through and keyframing it all?

  • Have a look at this guy's blend file: https://blender.stackexchange.com/q/86929/38953 He is using an amplitude curve from a digital recording to make icospheres dance. You may be able to make a script (or drivers) to use the amplitude values to "light up" certain cubes. – bertmoog Sep 21 '17 at 22:22

  • You can bake sound to an F curve and use that to drive any property (like brightness) there are plenty of videos online –  Sep 21 '17 at 23:21
  • You could also have a look at animation nodes. – sambler Sep 22 '17 at 06:10
