## What it is
OpenFracture is an open-source Unity package for procedurally fracturing and slicing 3D meshes at runtime or in the editor. It supports convex and non-convex closed geometry, UV remapping, custom interior materials, and recursive fragmentation.

## Use cases
- fracture meshes into pieces when objects are destroyed in Unity
- slice 3D models at runtime like cutting fruit in a game
- pre-fracture destructible props in the Unity editor
- shatter glass or walls into fragments on collision
- cut meshes with holes or non-convex geometry
- recursively break fragments into smaller pieces

## When to choose
- you need runtime or editor-time mesh destruction in a Unity project
- your meshes are closed and non-self-intersecting, including non-convex shapes
- you want tunable fragment counts and UV-preserving cuts without paid assets

## When to avoid
- you work outside Unity or need a standalone mesh-processing tool
- you need GPU-accelerated or multi-threaded high-performance fracturing
- your source meshes are open or self-intersecting geometry
