DinoFracture - A Dynamic Fracture Library

DinoFracture lets you take any mesh and break it apart at runtime or in the editor. It's a great addition for any developer looking to bring some life to their project.

With DinoFracture, you can break apart any mesh in your scene to create fragmented pieces. Meshes can be broken apart either at runtime or in the editor, allowing for optimal performance across all devices.

You can both shatter an object into many pieces (as in throwing a vase on the ground) or slice an object in half using user-defined planes (great for cutting enemies in half with a sword).

Example usages include:

• Break glass windows on impact
• Chip or crumble walls and columns
• Collapse a bridge by destroying its support pillars
• Explode barrels and crates
• Annihilate doors after activating a switch
• Smash fruit with a hammer
• Cut zombies in half

New in 2.10:

• Control the amount of vertex merging is done during fracturing. At runtime, you might want to use either a simpler & quicker vertex merging algorithm, or no merging at all, to reduce fracture time.
• Major performance improvements across the board! This is especially true when compiling with IL2CPP.

New in 2.9:

• Pre-fracturing can now be done at runtime. Get the benefits of pre-fracturing without increasing build-size. It is recommended to do pre-fracture computation during level load.
• Meshes generated by fracturing will now be more optimized. Less triangles and less vertices. This reduces times to calculate mesh hulls and saves on GPU rendering.

New in 2.8:

• Support for pre-fractured meshes with chipping enabled!
• Disconnected chipped sections will now fall automatically! Use the ChipOnFracture script in conjunction with GlueEdgeOnFracture on the fracture template for best results.

New in 2.5:

• Particle Collisions! Add the FractureOnParticleCollision script to allow collisions with particle systems to initiate a fracture. Particle impact can be transferred to the fracture pieces to simulate a pushing force. Be sure to check the "Send Collision Messages" option on the ParticleSystem!

Technical details

Features:

• Works with Unity 2018 - 2022
• Fracture any mesh, even while the game is running! Skinned meshes included.
• Shatter into many pieces or define your own slicing planes.
• Initiate shatters at a point of your choosing. Great for clustering pieces around a point of impact.
• Easy to use API with example scene included
• Detect and view mesh topology errors in the editor.
• Most common topology errors can be fixed during the fracturing process.
• Joints are transfered automatically when connected objects are fractured.
• Models can be "prefractured" for optimal performance directly in the editor. Slicing is fully supported by adding and manipulating slice planes directly in the scene view.
• Fracture many objects at once in the editor
• Works across all platforms, including WebGL
• Incredibly optimized results. The generated pieces produce the minimum amount of triangles required.
• Fracturing is threaded on platforms that support multi-threading.
• Many helper scripts to ease common functionality such as starting a fracture on collision, playing a sound effect when fracture occurs, and notifying other objects of fractures.
