Nope, sorry. You can with Bezier Warp though, if that’s any help.

Yeah, I think that’s pretty much it. I should have used a different variable name since f really represents half the period of the sine wave, not the frequency.

It’s just a sine wave that varies between -1 and +1. The sine wave is enclosed in a conditinal if/else so that whenever the value is between zero and one the opacity is set to 100, otherwise it is set to 0. So you really end up with the opacity being on for two seconds, off for two seconds, etc.

Hope that helps.

Forgot to divide by two. Should be:

freq = 2; //oscillations per second
intensity = 1; // max glow intensity
intensity*(1 + Math.sin(freq*time*Math.PI*2))/2

freq = 2; //oscillations per second
intensity = 1; // max glow intensity
intensity*(1 – Math.sin(freq*time*Math.PI*2))/2

Maybe something like this for one layer:

freq = 2; //oscillations per second
intensity = 1; // max glow intensity
intensity*(1 + Math.sin(freq*time*Math.PI*2))

and like this for the other layer:

freq = 2; //oscillations per second
intensity = 1; // max glow intensity
intensity*(1 – Math.sin(freq*time*Math.PI*2))
