Unlike Maya’s native Bullet solver (which is excellent for general rigid bodies but heavy for massive scenes), the PDI solver is optimized for progressive collapse. It handles: then navigate to PullDownIt >
Simulating 5,000 individual fragments is heavy. PDI allows you to simulate with Proxy geometry (simple bounding boxes) and then cache the motion. Once cached, you swap the proxies for the actual high-resolution fractured chunks. This keeps your viewport snappy.
Beyond simple falling, Pulldownit supports:
