Object tab menu for xpFoam.
Drag and drop an xpEmitter into this field to spawn foam particles.
Click this button to create a new spawning xpEmitter and add it to the Emitter link field.
This emitter will be used to create the foam particles.
This is the spawn rate (which can be fractional) for particles created at the crest of waves, using the Min Crest and Max Crest settings.
Animation to demonstrate a Crest Rate setting of 20, with a Min Crest value of 40% and a Max Crest of 100%, resulting in limited crest foam particles.
By comparison, in this animation, the Crest Rate value is increased to 85, with the same Min Crest and Max Crest settings. The result is increased crest foam particles.
The spawn rate for foam particles created as trapped air between colliding fluid particles (controlled with the Min Impact and Max Impact settings).
This animation demonstrates an Air Rate value of 20, with Min Impact set at 0 (zero) and Max Impact at 1.
With the same Min Impact and Max Impact settings, this animation demonstrates the effect of raising the Air Rate value to 85; generating more foam particles than with the lower setting.
Only those fluid particles which are older than this setting will create foam particles.
