The Seed slider and Randomize button are presented whenever a Fusion tool relies on a random result. Two tools with the same seed values will produce the same random results. Click on the Randomize button to randomly select a new seed value, or adjust the slider to manually select a new seed value.

This parameter sets the Strength of the force emitted by the tool. Positive values represent attractive forces. Negative values represent repellent forces.

This determines the degree to which the Strength of the force falls off over distance. A value of zero causes there to be no falloff of strength. Higher values will impose an ever-sharper falloff in strength of the force with distance.

The Limit Force control is used to counter-balance potential problems with temporal sub-sampling. Because the position of a particle is only sampled once a frame (unless sub-sampling is increased in the pRender tool), 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.

These controls are used to represent the X, Y, and Z coordinates of the point force in 3D space.
