How it works

Penpal works on shape layer Path properties, and Mask Path properties, and nothing else.
You cannot drag elements in the Penpal panel (e.g points) to move them, as you can in the main After Effects composition panel. You select elements, and then edit them with the button functions.

Loading Paths into Penpal

If you have a layer with one or more paths selected when you first open Penpal, it will automatically load them. Otherwise, select the layers or paths you want to edit, and either click the
reload button or double-click in an empty part of the canvas.
If you’ve loaded several paths, and you want to remove some from the panel, select them, then right-click anywhere in the panel to access the context menu, and click on Remove Path From View (you can also click Solo Path in View to remove non-selected paths).
