Falling Speed | foamFallLimit – Affects only the foam particles which are outside of the liquid volume. This parameter controls the drag force of foam flying through the air. The Falling Speed is also affected by the size of the individual bubbles. Lowering this parameter towards zero would cause foam to rapidly slow down when flying in the air, or hang in the air for a long time until it falls down. Note that this parameter affects only foam which is outside the liquid volume, while foam inside of the liquid mesh or which is mixed up with flying Liquid particles would have the same velocity as the liquid. In the second case, if the Falling Speed is too low, the foam might abruptly slow down at the moment it separates from the liquid that carries it. The scale of the option is in units/sec. For more information, see the Falling Speed example below.
