Unlock the creative power of Particle Illusion to create stunning, long-exposure light trails directly inside After Effects. In this comprehensive tutorial, Ben Brownlee shows how to transform standard text and mask paths into cinematic "light writing" animations using free professional presets.

There are two parts to this tutorial. You'll learn the essential workflow for driving particle emitters with text layers, including how to refine mask paths for a natural, hand-written look. Ben also covers advanced troubleshooting techniques to polish your final render. You'll fix common problems like eliminating unwanted trails between letters, tapering stroke thickness, and creating butter-smooth strokes without jaggies.

Finally, learn how to integrate your light trails into a 3D tracked scene, using After Effects' comp camera and expressions to ensure perfect scaling and placement. Whether you are creating motion graphics for titles or adding VFX to a live-action scene, these techniques will help you master particle motion paths.
