This panel allows you to describe the characteristics of the foam particles which are created when the bubbles reach the fluid's surface. The settings are exactly the same as with RealFlow's “Foam” emitter.
Surface offset
Foam particles are created from the core fluid's surface and with this parameter you can control how far away from the surface the particles will be placed. This parameter becomes interesting when you want to mesh the foam and waterline particles, because it can help to avoid flickering. "Surface offset" is given metres [m].
