Polyline is a plugin from Motion Boutique for After Effects that creates colorful, fully controllable animated polygonal lines. It runs on Apple Silicon and is offered on a name-your-own-price basis.
The plugin builds polylines from motion paths, and a few known constraints come with it. The total length of a polyline cannot exceed the maximum size of a composition, which is 30,000px. Some motion paths produce degenerate cases where a clean polyline cannot be constructed, such as a chain of orthogonal segments across the x, y, then z planes. Polyline relies on the built-in Corner Pin and CC Power Pin effects, which can occasionally show display issues, and modifying segment rotation can sometimes cause noticeable texture deformation.
Polyline has been discontinued, and the developer no longer provides support for it. A final version was released as name-your-own-price, adding After Effects 2023 compatibility and Apple Silicon support. It remains compatible with After Effects releases from CS5.5 through 2024.
