Slow random pulsating glow effect
on Mar 9, 2017 at 11:17:45 pm

My project has a red hot glowing object in it that I would like to add an expression to, in order to simulate the object cooling down in a slow and random pulsating manner. I saw Dan's pulsating glow equation, but it pulsated between 0 and 100. Also, the pulses were all equal, not random. My clip is only about 15 seconds long, so from beginning to end I would like to see the glow drop from 100 to maybe 50 while it is pulsating down in a random incremental fashion. Not looking for handouts, I'm working on it as I write this, but since I am new to expressions, I wouldn't mind a little help. Thank you.
