Evolution Stopped Evolving?
I have a 5min countdown clock with a fractal noise layer using the time*200 expression in the evolution. The evolution starts great and simply stops at 2:16… what the heck?
see it here…

a rundown of my setup…
top layor: black solid with feathered mask (vingette)
next layor: text layor with the following expression (thank creative cow)rate = -1;
clockStart = 300;
function padZero(n){
if (n < 10) return "0" + n else return "" + n } clockTime = Math.max(clockStart + rate*(time - inPoint),0); t = Math.floor(clockTime); min = Math.floor((t%3600)/60); sec = Math.floor(t%60); min + ":" + padZero(sec)next layor: a png of the shiney logo
next layor: a psd of the textured dark ribbon
next layor: a black solid with the following effects (in order)
-Fractal Noise: this has the evo expression time*200
-Fast Blur: 15
-CC Vector Blur: 20
(this layors tranfer mode is set to Classic Color Dodge)
final layor: psd layor of a colorful graphic I madethinking it had something to do with the time expression, i manually set a keyframe at the beginning of 0 evolution and at the end of 166x and it still stops at 2:16.
I’m stuck… please any ideas? -

I can’t duplicate the behavior using your time expression. It works fine for me. There must be something else going on.

isn’t that typical…
your car doesn’t start so you call your car buddy over to take a look. pop the hood and turn the key and the car comes to a roaring start… that’s life i guess.
thanks for trying, i suppose i’ll just make the countdown 2:45min instead of 5min. -
My Evolution only works between about -90x 0° and 91x 0° which Corresponds with your problem.
It has to do with the maximum allowed value for integers inside After Effects, and I think they are different for mac and PC. Sad that the value isn’t limited in the UI ie. that you couldn’t scrub the value above that value like you can’t set opacity to 101%
So:
In the evolution options, enable ‘Cycle Evolution’ and set Cycle (in Revolutions to a fairly high number that’s less than this limit, let’s say 80 in my case)then use this in your expression:
rev=360 * effect("Fractal Noise")("Cycle (in Revolutions)");
t= (time*200)%rev;

Um…
fixed and FIXED!
I’m all up and running now… thanks a ton Filip! -
Thanks Filip! I was stuck as well.

Great thank you very much! I had the same problem
It does not work for “turbulent noise” but it does work fine for “Fractal Noise”. -
THANK YOU!!!! This saved my bacon!!! Had a lovely handrawn effect that was only lasting for 20 seconds of a 3 minute video *face palm.
You are a gentleman and a scholar!
