A stylised energy shield implemented as one Shader Graph with modular, toggleable parts, so you can keep the full effect or switch features off to make it cheaper.

What’s in the graph

The graph exposes a boolean keyword for each feature:

  • Edge glow — brightens the silhouette.
  • Intersection glow — highlights where the shield cuts through other geometry, using Scene Depth.
  • Scanlines and a separate big scanline sweep.
  • Hexagon overlay — texture-driven cells with animated noise glow.
  • Collision ripples — a ring that expands from a world-space hit point (Ripple Origin, Ripple Time), set by the included script.

A second, smaller graph (SceneIntersections.shadergraph) isolates the depth-intersection technique on its own, which makes it a useful reference.

Notes

The repository is a complete Unity project rather than a package: open it in Unity 2021.3, or copy Assets/Shaders, Assets/Scripts and Assets/VFX into your own URP project. The impact sparks use VFX Graph, which needs compute-shader support on the target platform.
