Procedural Weapon Trails

How It Works: Procedural Weapon Trails uses VFX Graph to create trails in real time with minimal setup. Add one script component, pick from 35 ready-to-use effects, and your trails work immediately. The system handles any skinned mesh or can be controlled manually. You can even run two trails at once for dual-wielding. The system includes both performance-focused fast templats and advanced smooth trail template powered by dual-spline Cardinal and Hermite curve evaluation. Sub-frame arc-length interpolation guarantees completely smooth, continuous trails regardless of framerate, motion scenario, or weapon velocity, eliminating sharp angles and ribbon twisting during high-speed rotational swings. The built-in animation editor removes all the usual hassle with timing the start/end of slashes. Use two sliders to set when trails appear, click to choose an effect, and you're finished. No custom meshes required. No animation events needed. No technical complications. Trail Library: 35 Effects Across 8 Styles (Stylized, Water & Wind, Claws, Sorcery, Simple, Celestial, Subtle, Fire). Every effect works out of the box and can be adjusted with live preview.
