The open-source project is based on Nvidia Blast.
Have a look at Unity Libre Fracture, a free and open-source fracture system developed for Unity by Dmitry Senyushkin. The system uses NVIDIA Blast wrapper for Unity as a base. As for concave meshes, it uses VHACD (Volumetric Hierarchical Approximate Convex Decomposition).
The developer also plans to improve and add a number of things:
- Fix physical stability issue, probably related to the centers of masses (can be noticed on round objects like spheres when fractured)
- Distribute mass along chunks with taking their size into account
- If FractureObject had any joints attached and it was then fractured, make corresponding joints at the chunk(s) to the same connected body
- Mesh deformation system
