Hey John! Thanks for the response. I’ll be sure to read up on the AE material you linked.
Right now, I got the line to go down by creating a solid > effect > generate > write-on. I adjusted the brush size, etc… to what I wanted, but I can’t figure out how to get the line to retrieve. After the stroke length time is up, the line descends down upon itself. I would like for it to ascend up instead.
I tried your approach with creating a solid > pen/mask, and created a straight line to descend down. But again, I couldn’t figure out how to bring it back up. How do I go about editing the stroke “end” parameter?
