Trail FXs is a collection of geometry node templates designed to generate procedural trailing effects for animations. It utilizes simulation nodes to create dynamic trailing lines, weapon trails, and particle emissions. The tool allows for custom blade shapes, enabling trails on non-linear objects like wings or irregular weapons. Users can control trail length, smoothness, color, and glow strength through modifier sliders without editing the node tree directly.

The system includes over 30 customizable trailing materials and supports both Cycles and EEVEE render engines. It features asset browser integration for easy access to its templates, which include basic trails, liquid trails, smoke effects, and particle collision systems. The setup also supports custom particle shapes and includes multiple basic and blade trail variations.
