Spline Path FX

Spline Path FX brings stunning, animated path-based effects to 3D space using Unity's official Spline system and high-performance mesh-based shaders. Whether you're creating sci-fi trails, energy flows, magic beams, or stylized UI transitions in 3D, this plugin lets you do it all — no code required.

This package includes all features from UI Path FX, and expands them into full 3D support with MeshRenderer-based workflows.

🔧 How It Works

Built on Unity’s Spline system, Spline Path FX dynamically generates mesh geometry along spline paths and applies multi-layered animated textures with fine-tuned UV control.

Each shader allows:

• Independent UV speed/direction per layer
• Global edge fading for better compatibility with non-uniform or irregular textures
• HDR color overlays for vibrant, customizable visual styles

All shaders share a unified logic, so you can learn one and easily adapt the rest — with a Quick Start Guide scene that gets you up and running in under 10 minutes.

🎮 How to Get Started

1. Find the Spline Object
   Look for GameObjects with a Spline component in your scene.
2. Edit the Spline Path
   In Scene View, switch to Spline Edit Mode and manipulate control points to define your desired curve.
3. Select the Spline Path FX Example Object
   Modify the included prefab and review its Spline Path FX component.
4. Tweak Shader Settings
   In the Material Inspector, adjust UV animation parameters and test different shaders from the UVAnim/ folder.
