There were a few things changed with the Grease Pencil since this video was created. Instead of duplicating it the way he did, I tested it out by duplicating it from the “Asset Shelf” at the bottom of the screen. Then I proceeded to follow the steps he did. Where he tweaked “UV”, I think I changed “Rotation”. I also lowered the Spacing under the Advanced options to make the dots appear closer together. I couldn’t find the curves he adjusted, though, but pretty much everything else I did was just like he did in the video.
