Spline Path FX

Spline Path FX brings stunning, animated path-based effects to 3D space using Unity's official Spline system and high-performance 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 And LineRender-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.
