Pressure keeps the volume alive.
This native Ammo study follows the pinned soft-body volume example: a sphere and a subdivided box keep their pressure while colliding with a ground plane, ramp, and thrown rigid balls.

Click the scene or use Throw ball to follow the source ray/velocity path. Deterministic controls expose native pressure, collision, node, and normal behavior without claiming exact official texture, Stats, pixel, or whole-example fidelity.
