Foam buoyancy with SPH
The top video shows a foam density factor of 1, which means that generated foam is not subject to any buoyancy. On the contrary, the bottom video shows a foam density factor of 0.5, which means that generated foam is half the density of the liquid which generates it so it rises to the surface.
