Transform Affector
Updated: 12 Jun 2026
Affects the position and rotation of physics objects based on the transforms of a given target.
Transform Affector
Method #
The node uses the transforms of a target node to influence rigid bodies within a physics system. The target can be a single object or a set of cloned objects. Rigid bodies that fall within the influence of the target node(s) will attempt to match the position and rotation of their corresponding targets.
The Amount and Angular Stiffness parameters control how strongly the rigid bodies are driven towards the target transforms. Higher values cause rigid bodies to follow the target position and rotation more closely, while lower values allow the influence to be applied more gradually, preserving more of the natural physical motion and simulation behaviour.
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.
Parameter Details 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.

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.
Parameter Details Amount
Controls how strongly rigid bodies attempt to match the target position.
Angular Stiffness
Controls how strongly rigid bodies attempt to match the target rotation.
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.
- Vortex : Apply an orbital motion around the centre point.
Target Pivot X
Sets where the center of influence is of the target on the X axis.
Target Pivot Y
Sets where the center of influence is of the target on the Y axis.
Target Pivot Z
Sets where the center of influence is of the target on the Z axis.
Target Falloff
Apply a falloff to the influence of each target.
- Off : Affector will be applied evenly to all rigid bodies in the scene.
- On : Affector influence increases from 0% at the outer falloff to 100% at the inner falloff.
Target Falloff Inner
Affectors influence will be at 100% inside this radius.
Target Falloff Outer
Affectors will have no influence outside of this radius.
Target Falloff Power
Adjusts how rapidly influence increases from the outer falloff to the inner falloff.
Dampening
Applies resistance to motion, reducing velocity and creating smoother movement.
Randomness
Adds randomness to the amount of positional and rotational influence the affector has.
These properties are used to set the falloff of the node.
Parameter Details Falloff Mode
Which shape to use to calculate the falloff.
- Off : No falloff is used. Everything will be affected equally.
- Spherical : Falloff is drawn outward from a central point, forming a spherical falloff.
- Cylindrical : Falloff is drawn outward from a line, forming a cylindrical falloff.
- Planar : Falloff is drawn outwards in one or both directions from a plane, forming a planar falloff.
- Procedural : Uses a connected procedural system to describe the falloff area. A procedural system must be input for this property to function.
- Cubic : Falloff is drawn from the sides of a cube.
Falloff Axis
Which axis the falloff should be oriented on.
Falloff Direction
When using Planar mode, which directions to use to calculate the falloff.
- Bidirectional : The falloff applies in both directions from the plane.
- Negative : The falloff applies only in the negative direction from the Fallof Axis. The positive direction has the full effect applied.
- Positive : The falloff applies only in the positive direction from the Fallof Axis. The negative direction has the full effect applied.
Falloff Easing Mode
Interpolation method used to calculate the falloff within its range of influence.
- Linear : Falloff reduces linearly across the falloff range.
- Sine : Falloff reduces using a sine function across the falloff range.
- Quadratic : Falloff reduces using a quadratic function across the falloff range.
- Cubic : Falloff reduces using a cubic function across the falloff range.
- Circular : Falloff reduces using a circular function across the falloff range.
- Bounce Back : Falloff uses a function which as values reach the edge of the falloff range, they will overshoot and bounce back.
- Elastic : Falloff uses a function similar to bounce back, but the value will initially move in the opposite direction, creating a “pull and release” effect.
Falloff Size X
Size of the falloff range along the X axis.
Falloff Size Y
Size of the falloff range along the Y axis.
Falloff Size Z
Size of the falloff range along the Z axis.
Outer Range
Outer range of the falloff, outside of which the falloff is no longer effective.
Inner Range
Inner range of the falloff, inside of which the falloff is fully effective.
Curve Power
Controls the rate of change for the falloff between the inner and outer range.
Invert
Inverts the effect of the falloff.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
