Motion Stroke FX is an asset library that enables the creation of dynamic, doodle-style animated line effects using simple curves. Users can drag the assets directly into the scene, draw out paths, and adjust modifier parameters to control the timing and look of the animation. The included geometry setups are highly customizable, featuring specific controls for adjusting frame rate variations on certain stroke types.

Beyond generating standalone line elements, the effects can be applied to standard objects in the scene. Dragging the asset onto an existing mesh introduces stylized jitter and displacement behaviors, making it easy to apply consistent doodle-style motion across multiple scene elements.
