i using wiggle expression extensively in project, , starting notice if render part of render 1 day, render rest again day, set of wiggle values different each time , animation jumps undesireably. doing stereo 3d , have render right eye, left, keep wiggle values right each eye.
my question is, how long random values chosen wiggle expression persist? session? if save document , quit, open again , render another, different random wiggle values? how can count on chosen random values chosen wiggle stay same? event causes expression go through , choose set of new random values?
i prefer not "bake" values keyframes. want understand persistence rules know i'm against.
random seed persistent. doesn't randomly change on day day basis. automatic seeding of course different every layer , every comp , responds time, changes when change layer order or move in point or that. there may differences legacy projects when opened in cs6, because randomization algorithm has changed. anyway, can pin specific random seed using seedrandom(value,true) preceeding wiggle.
