Unlike real-time physics engines that cut geometry on the fly (which can be unstable), Pulldownit uses a . You tell the plugin how to break an object (Voronoi patterns, uniform grids, or custom shards), and it creates a network of interconnected fragments before the simulation starts. During the animation, these pieces are held together by "glue" until an impact breaks the bonds.
I simulated a collapsing Roman ruin—roughly 2,500 fractured pieces. Native Maya Bullet crashed on my second test. Pulldownit handled it like a champ on a standard laptop. pulldownit maya
