creating a LOOPED wiggle with RANGE SELECTION
Let’s say I want to create a looped wiggle on the rotation property, but I only want it to move between two values (let’s say, -35, 40). how can I do something like this?
I would love to have a global wiggle expression that will give me maximum control (min value, max value, loop time).
Thanks a lot for the help 🙂

The best I could come up with is something like this. It will be approximate because you never know exactly what you’ll get min and max wise with wiggle. You’ll need to tweak ampAdjust (an amplitude multiplier) and offsetAdjust (to move the whole waveform up or down) after you see what you get if you need it to run exactly from minVal to maxVal.
freq = 10;
maxVal = 40;
minVal = -35;
loopTime = 3;
ampAdjust = 1.25;
offsetAdjust = -2;
t = time % loopTime;
amp = (maxVal - minVal)/2
wiggle1 = wiggle(freq, amp, 1, 0.5, t) - valueAtTime(t);
wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime) - valueAtTime(t);
w = linear(t, 0, loopTime, wiggle1, wiggle2)*ampAdjust;
offset = (maxVal + minVal)/2;
value + w + offset + offsetAdjust
