Fragments will remain perfectly still until the physical impact or field touches them, resulting in a controlled, realistic explosion or collapse. Pulldownit vs. Maya Bifrost and Bullet
Never let your impact objects intersect with your target rigid bodies on frame 1. This causes the solver to generate mathematical infinite forces, throwing pieces uncontrollably across the viewport.

PDI is designed for faster computation and lower overhead when simulating massive amounts of debris.
Fragments don't just fall apart instantly; they can hold together structurally until an external force exceeds their predefined material strength. 3. Progressive Cracking (Dynamic Fracture)
