    I’m pretty new to expressions. I want to add a transparency wiggle to the letters in a word but I want to form a seamless loop. Any help would be appreciated

    – Create Text-layer

    – select Animate -> Opacity and set it to 0

    – remove the default range selector

    – add a Wiggly Selector

    – set its Wiggles/second to 0 !

    – give Temporal Phase this expression:

    loop = 10; //loops in 10 seconds

    wiggles=1;

    Math.cos(time*6.2831853071/loop)*wiggles*360*loop/6.2831853071;

    – give Spatial Phase this similar expression (cos -> sin):

    loop = 10; //loops in 10 seconds

    wiggles=1;

    Math.sin(time*6.2831853071/loop)*wiggles*360*loop/6.2831853071;

    You can still tweak Random Seed and Correlation, but Wiggles/Second parameter has to be 0 or it will not loop. The wiggles variable in the expression is equivalent to wiggles/second.

    (6.2831853071 = 2*pi)

    It worked perfectly!

    Thanks so much
