Liner Tool is a geometry nodes modifier designed to generate and animate outlines for text and shape objects. It provides functionality similar to stroke effects found in After Effects, allowing you to create complex graphics and titles.

The system includes multi-spline support and dual outline cores, featuring both curve-based and grid-based generation methods. The grid core can be aligned at various angles relative to the base curve, with inside and outside options. Tentacle effects can be added to the outlines, featuring noise, voronoi, spiral, and tilt-offset properties available in both 2D and 3D space.

Additional features include particle integration and background illumination options, which are particularly optimized for the EEVEE render engine. The modifier supports smooth animation with loop and manual controls. The grid core also provides dynamic and still options, beneficial for non-cyclic curves. The tool is provided as an asset library and can be appended directly into new scenes.
