3 Point Loop for Wiggle Expression.
I want to know if I can set parameters for a wiggle expression to have a 3 point loop. This is my current wiggle expression
wiggle(.5,23)
My comp is 516 frames and I need the loop point to be at 33 frames.
I found this online but I don’t quite understand it so I’m not sure if it can be edited for what I need, but here it is.
Thanks for any help.
-Lisafreq = 1;
amp = 110;
loopTime = 3;
t = time % loopTime;
wiggle1 = wiggle(freq, amp, 1, 0.5, t);
wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime);
linear(t, 0, loopTime, wiggle1, wiggle2) -

What do you mean by “3 point loop”.

The animation starts at frame 1, ends at frame 516 and will loop back to frame 33. I need my wiggle expression to do the same.

See if this does what you want:
loopStart = framesToTime(33);
loopEnd = framesToTime(517);if (time < loopStart){
wiggle(.5,23);
}else{
dTime = loopEnd-loopStart;
t = (time - loopStart)%dTime;
offset = wiggle(.5,23,1,.5,loopEnd) - wiggle(.5,23,1,.5,loopStart);
wiggle(.5,23,1,.5,loopStart+t) - linear(t,0,dTime,0,offset)
}

WOW! Thank you so much, this works perfectly.
