Fill in the backdrop with the frames for an animation (or use the sample animation), and click the green flag. The project will then scan the animation, and then when you press space, it will run through the animation but drawn in pen!
Thanks to Mix0412 for their color picker block. All other coding done by me. NOTE: Images with lots of colors (such as actual photos) will take longer to scan. Tags: #pen #animation #sanner #quick #render
