![]() ![]() ![]() This option has no effect if Variation Large is 0. Size Distribution | fszdstrb – Specifies how many times the amount of bubbles with radius Size exceeds the amount of the largest bubbles. For more information, see the Variation Large example below. You can also use the Distribution parameter to control the balance between the number of small and large bubbles. 10 means that the largest bubbles are 11 times larger than Size. 1 means that the largest bubbles are two times larger than Size. 0 means that all bubbles are never larger than Size. ![]() Variation Large | fsizevar – Specifies how much larger the bubbles can be, relative to the Size parameter. For more information, see the Variation Small example below. 10 means that the smallest bubbles are 11 times smaller than Size. 1 means that the smallest bubbles are two times smaller than Size. ![]() 0 means that all bubbles are always at least as big as Size. Variation Small | fshrink – Specifies how much smaller the bubbles can be, relative to the Size parameter. Larger bubbles rise faster while they are underwater, while smaller ones rise more slowly. The difference between this approach and spawning foam inside a volume manually from a Source object is that using a Birth Volume, the foam birth will follow the simulation criteria of the simulation and will look and behave more naturally. The foam born inside the Birth Volume can travel outside the volume without a problem. This includes foam born according to the conditions set by the Foam Amount and Birth Threshold parameters of the Foam, as well as the Foam on Hit parameters of the Splash. For more information, see the Birth Threshold example below.īirth Volume | usefbconfgeom, fbconfgeom – When enabled, allows the foam to be born naturally by the simulation only inside a specified geometry object. This means that the lower this option is, the more foam will be born and also the more places in the Simulator would allow foam to be born. If the difference in velocity between two neighbor voxels is higher that this threshold, foam particles should be born. This parameter does not affect the foam born by splashes.īirth Threshold (units/sec) | fbthres – Foam is born where the liquid movement is turbulent. Foam Amount | fbirth – How many foam particles are born in the places where the Birth Threshold condition is met, in particles per cubic centimeter, per second. ![]()
