Physics is expensive. Simulating the rigid body physics of 500 stone blocks can bring a lower-end PC to its knees. Detonate 1.2 introduced a dynamic LOD (Level of Detail) system for physics. When a building is standing, the physics engine mostly ignores it. As it collapses, physics objects are activated. Once the dust settles and the pieces stop
in real-time, meaning buildings don't just "break"—they buckle and fail realistically based on which support columns you remove. Key Features of the Building Pack detonate 1.2 building pack
One of the most tedious parts of implementing destruction is the modeling process. An artist has to take a whole model, cut it into hundreds of pieces, and unwrap UV maps for every single shard. Physics is expensive
