falloffStart
The depth (in meters) inside the volume at which the total force starts to linearly fall off.
Declaration
var falloffStart: Float { get set }Discussion
For particles whose depth is greater than or equal to falloffStart, the full force is applied. For shallower particles, the force ramps linearly from zero at the volume surface to the full force at falloffStart. Must be non-negative; negative values are clamped to zero. Zero by default, which means the total force is fully applied to all intersecting particles.
