Polyline is simply broken with the latest After-Effect version 2020. Nothing seems to work as it should even after reverting to Legacy extended script in AE file preferences. I bought the plug-in because I needed the kind of ribbons it creates, and I needed it fast. I have waste an entire night of work trying to figure out what I was doing wrong. But it's not me, it's the plug-in ! I now ask for a refund please. You should really keep your products up to date if you sell them.
