Fluid is one of three Physics Models used by the Physics group. The Fluid model is used to make particles move in a pattern similar to liquid.
If you're looking to add additional fluid emitters, performance will be much faster if you work within one instance of Particular. Adding fluid emitters on separate Particular instances on separate layers will increase render times dramatically.
Defines what type of force is applied to the liquid particles
Apply Force pop up
Determines if the force dictated above is applied Continuously, or only once (At Start) of the effect.
Force Relative Position
A set of X, Y, Z coordinates which determine where in relation to the emitter the forces defined above are applied to the particles.
Force Region Size
Determines the region around the emitter in which the force affects the particle's positions.
Defines how much upward (positive) or downward (negative) force is applied to the particles.
Random Swirl X, Y, Z
This controls how turbulent swirling forces are applied along the X, Y, and Z axis of the particles. The higher the number, the stronger the forces and the further the particles travel from their original position.
Adjusts size of the forces used to create swirl effects; low values produce large swirls, while higher values create smaller swirls.
Adjusts the integer used to create a random effect. Changing this will help give one fluid particle system a slight variation from any others sharing the same parameters.
Controls how fast the vortex is spinning, which increases and decreases the strength of its force on the fluid particles.
Vortex Core Size
Adjusts the diameter of the vortex forces used to spin the fluid particles.
Tilts the vortex forces along the axis of the buoyancy force.
Rotates the vortex forces around the axis the buoyancy force.
Note that this will only have a noticeable affect when the vortex tilt has been adjusted.
Visualize Relative Density
Control particle appearance with relation to the combined density of the particles and the fluid forces surrounding them:
