Dear Dan,
I´m using the expression you suggested to get a random number between 1 and 5.
Yet I´d like to have this expression to be re-evaluated so I can end up with a different value the next time I open the after effects project.
Eg. let´s say the 1st time I open the file its value is 3 and if I load the file again the value changes (within the range of course)
seedRandom(index,true);
random(1,5);
