I've been looking for a good solution to this for awhile. I'm making a whiteboard style animation, with a pen that moves about generating ink, to create the illusion of images and words being drawn on. Trim paths is fast, but there's no positional data to animate my pen with. The Write-On effect works for simple drawings and words, but with a complicated drawing it becomes time intensive to animate brush-size and opacity, so that strokes don't overlap, especially over the course of a 2 minute video.
I went through many resources and also checked a lot of whiteboard animation examples but did not find anything much related to what I am looking for.
Any help will be appreciated.
