Introduction

Trails FX is a fast, lightweight Unity package for adding smooth trails to moving GameObjects, characters, and weapons. It supports the Built-in and URP rendering pipelines on Unity 2022.3 and later.

Key Features

• Multiple trail styles — Color, Texture Stamp, Clone, Outline, Space Distortion, Dash, and Custom material
• Skinned mesh support — trails follow animated characters with per-vertex accuracy
• Flexible triggers — generate snapshots on movement, time interval, collision, or continuously
• Color Ramp — map a gradient texture along a blade or edge (ideal for sword trails)
• Animation state filtering — restrict trails to specific Animator states and time ranges
• Profile system — save and reuse trail configurations across multiple objects
• Draw Behind — render trails behind the character using the stencil buffer
• Zero per-frame allocation — GPU-instanced rendering with pooled meshes
