Getting a lot better!
About your node setup for the lights:
you are multiplying a random value, between 0 and 1 with a number that goes from 0 to 1 over time (when you have 250 frames…). This means that if the random value is close to 0, hardly any change will happen over time (red lights stay red….blue lights start red and go through the ‘whole’ colorramp to blue). I don’t think that is what you actually want.
And as an unimportant side note: multiplying 2 numbers between 0 and 1 always gives a result between 0 and 1, so there is no need to Clamp the Multiply Node…apart from the fact that the Colorramp Node also clamps its input…it’s overly careful, a bit like wearing a mask while in quarantaine 😉
Here is what you could do for instance:
If you want to use a colorramp for more control over the colors, you need an extra Math Node,:
Fraction or Modulo 1 both do the trick, but the values will jump from 1 to 0 (I mean like:…, 0.99, 0, 0.01, …). You’d need to take that into account with the colorramp colors.
If you don’t mind it going back and forth, you could set the second Math Node to Ping Pong (for a linear speed), or use a Sine, but then you need to adjust its input…
Still, I applaud the effort you made!
