A complete, code-free solution for adding smooth, framerate-independent weapon trails to any character. Dual-spline interpolation guarantees flawless motion without meshes, baking, or events.How It WorksProcedural 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 Library35 Effects Across 8 Styles:StylizedWater & WindClawsSorcerySimpleCelestialSubtleFireEvery effect works out of the box and can be adjusted with live preview.What You GetSingle-component integrationSmooth dual-spline Cardinal and Hermite interpolationFPS-independent sub-frame trail evaluationDedicated Fast and Smooth rendering workflowsLive animation previewTrail saving and loading systemTwo trails per characterDistortion effectsWorks with quick strikes and long slashesC# API for custom controlDocumentation & SupportThe asset includes five interactive demo scenes, video tutorials, and detailed guides with images that walk you through every step.Join the Discord community for updates and support.Full documentation: Procedural Weapon Trails GuideCompatibilityUnity 6.0 or newerURP or HDRP (VFX Graph required)Editor Coroutines package requiredLow-end mobile devices are not recommended (see documentation)The asset does not include all 3D models used in the Asset Store page promotion video or screenshots (e.g., Mixamo characters - knight, magician, warrior with axe, mutant).
