looping a wiggle expression

[Robert Paynter]

well.. i came up with a solution of cutting the comp in half then duplicating, reversing then tagging it on the end.. it now “swings”. I am still interested in finding out if there is a way to loop random expressions..

The only way I find out is to convert random expresion to keyframes and then made some dublicates …

There are three ways that I know of, all using wiggle’s 5th parameter (time):

1) Halfway through the loop you run the time parameter backwards. This is the easiest but least convincing way.

2) Calculate the difference between the wiggle values at the start and end of the loop and subtract an amount of that difference proportional to where you are in the loop (so you end up back where you started).

3) This one is hard to describe, but might be the best. Halfway through the loop, you re-run the same wiggle but flipped over and starting from the halfway point. One way to picture this is to make two copies of a wiggly path. Flip one over and match up the endpoints so that it makes a closed loop.
