Advanced Outline Shader

The Advanced Outline System is a clean, modular, and high-performance screen-space outline solution designed to easily highlight interactable objects, selected units, or occluded characters in your project. Natively compatible with both the Built-in (Standard) Render Pipeline and the Universal Render Pipeline (URP), the package automatically detects your project settings at runtime and loads the appropriate shaders dynamically. Whether you are developing a puzzle game (hover highlights), a stealth game (viewing enemy silhouettes through walls), an RPG (loot highlights), or an RTS (unit selection), this asset is fully customizable and genre-agnostic. Outlines are calculated dynamically via a multi-pass stencil technique. To ensure outlines look clean even on low-poly or hard-edged geometry, the system includes a normal smoothing utility that averages vertex normals in memory. A custom, user-friendly inspector editor allows you to easily manage settings and bake smooth normals directly inside the editor to prevent runtime loading spikes.
