Method #

This node applies a constant force on physics objects. This is typically used push and pull objects towards or away from the subject.

All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.

Parameters

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

ParameterDetails
Position X The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects scale along the local z-axis.

Control the inheritance of the transforms from the parent.

ParameterDetails
Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Amount Strength the affector has on the affected physics objects.
Dampening Softens the motion applied to the objects to smooth out any erratic motion from the affected physics objects.
Randomness Randomises the force amount per object.
Mode The mode of the affector
  • Directional Force : Apply a constant force in a single direction.
  • Repel : Apply a constant force outwards from the centre point.
  • Attract : Apply a constant force inwards to the centre point.

These properties control where an affector can affect the physics objects.

ParameterDetails
Use Falloff Enable falloff from the position of the affector.
Falloff Shape Select which shape to use to draw falloff from.
  • Sphere : Falloff is calculated radially outward from a point.
  • Cylinder : Falloff is drawn radially outward from a line.
  • Plane : Falloff is drawn outward from a plane.
Falloff Shape Orientation Select which axis to draw the shape along. Only available for cylinder and plane.
  • X : Faces along the x axis.
  • Y : Faces along the y axis.
  • Z : Faces along the z axis.
Outer Range The maximum range outside of which the affector has no effect.
Inner Range The inner range within which the affector has full affect.
Falloff Curve Power How quickly the falloff decreases to the outer falloff.
Invert Falloff Inverts the strength the affector will have on the objects, based on the falloff.
