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?

  • $\begingroup$ Have a look at this guy's blend file: 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. $\endgroup$

  • $\begingroup$ You can bake sound to an F curve and use that to drive any property (like brightness) there are plenty of videos online $\endgroup$
