## What it is
An outline image effect library for Unity that renders outlines around sprites, lines, and meshes via a camera component and per-renderer Outline components. It supports HDR, alpha cutout, additive rendering, merged outlines, and per-renderer colors.

## Use cases
- highlight selectable objects in a Unity game with outlines
- add outline effects to sprites and meshes in Unity
- render colored outlines around characters for hover/selection feedback
- create bloom-friendly HDR outlines in Unity
- merge outlines between adjacent renderers

## When to choose
- you need a free, open-source outline effect for Unity
- you want per-renderer outline colors and sprite/mesh/line support
- you prefer installing via OpenUPM, Package Manager, or the Asset Store

## When to avoid
- you use a game engine other than Unity
- you need post-processing effects beyond outlines
- you require actively developed features or recent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing, graphics
- domain: graphics
