Your expressions add value to your work. I hope you enjoy it! The wiggle () expression is not affected. For example, this expression on the Opacity property sets the Opacity value to a random value that does not vary with time: seedRandom, true ); random () * 100 The multiplication by 100 in this example converts the value in the range 0–1 returned by the random method into a number in the range 0–100 ; random value expression after effects random value expression after effects this range is more typically useful for the Opacity property, which has values from 0% to 100%. Value expressions show whatever the current value random value expression after effects is, and random value expression after effects will change according to keyframes as well. It picks a random number for the opacity value the layer only some of the time, based on whether another random number ("probability") is less than or equal to 1.
