Basic Node Setup
The pPoint Force node is inserted between a pEmitter and a pRender node.
The pPoint Force node positions a tangent force that particles are attracted to or repelled from

Randomize
The Random Seed slider and Randomize button are presented whenever a Fusion node relies
on a random result. Two nodes with the same seed values will produce the same random
results. Click the Randomize button to randomly select a new seed value, or adjust the slider to
manually select a new seed value.
Strength
This parameter sets the Strength of the force emitted by the node. Positive values represent
attractive forces; negative values represent repellent forces.
Power
This determines the degree to which the Strength of the force falls off over distance. A value of
zero causes no falloff of strength. Higher values will impose an ever-sharper falloff in strength of
the force with distance.
Limit Force
The Limit Force control is used to counterbalance potential problems with temporal sub-
sampling. Because the position of a particle is sampled only once a frame (unless sub-sampling
is increased in the pRender node), it is possible that a particle can overshoot the Point Force’s
position and end up getting thrown off in the opposite direction. Increasing the value of this
control reduces the likelihood that this will happen.
X, Y, Z Center Position
These controls are used to represent the X, Y, and Z coordinates of the point force in 3D space.
