In brief: Dmitry Senyushkin released Unity Libre Fracture, a free and open-source fracture system for Unity.
How it worked: The project used an Nvidia Blast wrapper as its foundation and employed Volumetric Hierarchical Approximate Convex Decomposition (VHACD) for concave meshes. The VHACD repository documented the underlying decomposition approach.
Planned improvements included greater physics stability, better mesh deformation and mass distribution that accounted for fragment size.
The project was hosted on GitLab, with demonstrations and guidance on the developer’s YouTube channel.

Audit the repository, licence, dependencies and native binaries, then test Unity-version support, collision, fragment counts, mass and performance before production deployment.
