## What it is
Skinner is a Unity library of special effects that use the vertices of an animating skinned mesh as emitting points for particle and trail effects. It converts vertex positions into GPU-friendly data via replacement shaders, avoiding extra CPU and memory overhead.

## Use cases
- create particle effects that follow an animated character's body
- make motion trails from skinned mesh vertices in Unity
- add GPU-driven VFX to a rigged character
- emit particles from a deforming mesh without CPU readback
- build stylized character dissolve or glitch effects

## When to choose
- you use Unity and want vertex-based character VFX with minimal CPU cost
- you need particle or trail effects driven by skinned mesh animation

## When to avoid
- you work in a game engine other than Unity
- you need general-purpose CPU-side mesh processing
- you need actively maintained tooling - the last release was in 2019

## Facets
- artifact type: library

- function: graphics, simulation, image-processing
- domain: graphics
- platform: game-engine, cross-platform
