Usually I use Effect -> Generate -> Stroke and animate the Start or End keyframes to reveal the stroke over time. I can't this time around because I need a stroke fatter than 50 pixels - the max for this effect.
So I made a Stroke Shape Layer ... but cannot for the life of me get it to reveal from 0 to 100%.
Am I blind? Two other colleagues couldn't do it either ...
You need to apply a Trim Paths modifier to get that functionality... It even offers properly capped strokes without extra effort. How's that sound?
I'm embarrassed - I pulled out the Add triangle but when I saw "Pucker, Round, Twist, Wiggle etc.." I thought 'I'm not looking for these Illustrator-like distortions..' and my eyes skipped right over Trim.
