Spring Effector
Updated: 4 Dec 2023
Modifiers a cloner system by adding a springiness to Clone transformations.
Spring Effector
Method #
This node provides a springiness to clones by keeping track of their original positions before being effected and pulling them back into position.
Unlike other cloner nodes, this Effector is a simulation node. This means that jumping in time will not produce predictable results, as the simulation needs to process the frames in between.
Connect the output to the effector input of any cloner node to apply it to the camera system. Multiple effectors connected to the same output will stack, and order of operations chosen by position on the nodegraph.
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.
Scale Z
The objects scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details 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.
Parameter Details Blend Amount
Controls the amount the resulting transforms of each clone after the effector is applied is blended with the original transform.
Space
The transform space the Effector uses to influence the clones.
- Effector - World : Use the world space transforms of the effector to influence the clones.
- Cloner : Use the transforms in local space to the cloner to influence the clones.
Animation Rate
How quickly the effector animates across the clones.
Spring Speed
How quickly the clones are pulled back to their original positions.
Spring Dampening
How much dampening is applied to the movements of the clones, so that they eventually slow to a stop.
Update Time Mode
Change how the clone animation uses time.
- Locked To Timecode : The effect is synchronised with the timecode, so changes in time will always yield the same results.
- Running / Loopable : The effect is generated on a separate time to the timecode, ignoring composition loops. Useful for Real-Time exports, where content needs to play indefinitely. Not suitable for looping videos.
Spring Mode
The method by which the clone position to spring back from is determined.
- Effectors In Chain : All clone effectors before the Spring Effector in the chain - anything moving the clone away from its initial position - determine the spring position.
- Effector Children : Only effectors parented to the Spring Effector will determine the spring initial position.
These properties control where an effector can affect the clones.
Parameter Details Falloff Mode
Change how the falloff from the original object is calculated.
- Infinite : There is no falloff, all objects will be affected equally.
- Linear : Falloff is based on distance from an infinite plane along a chose axis.
- Sphere : Falloff is based on distance from the plain effectors origin.
- Procedural : Uses a connected procedural system to describe the falloff area. A procedural node must be input for this property to function.
- Box : Falloff is based on the distance around a box based at the effectors origin.
Linear Falloff Axis
The falloff axis to use when the effector is in linear mode.
- +X : The positive x axis.
- -X : The negative x axis.
- +Y : The positive y axis
- -Y : The negative y axis.
- +Z : The positive z axis.
- -Z : The negative z axis.
Falloff
The outer radius of the falloff, where the effector no longer effects the clones.
Inner Falloff
The inner radius of the falloff, where the effector effects the clones strongest.
Falloff Power
Change how quickly the nodes falloff from the effector
Falloff Size
The X size of the falloff when in box mode.
Invert Falloff
Invert the direction of the falloff.
These properties control how an effector transforms the clones.
Parameter Details Position X
Offset the clones x position from the current position.
Position Y
Offset the clones y position from the current position.
Position Z
Offset the clones z position from the current position.
Rotation Heading
Offset the clones y rotation from the current rotation.

Apply To Position
Apply the position changes from the effector to the clones.
Apply To Rotation
Apply the rotation changes from the effector to the clones.
Apply To Scale
Apply the scale changes from the effector to the clones.
Position Apply Mode
The method by which the effectors position properties are applied to the clone.
- Add : The effector position is weighted by the falloff and added to the clone position.
- Multiply : The effector position is weighted by the falloff and mutliplied to the clones rotation.
- Replace : The effector position is weighted by the falloff and replaces the clones rotation.
Rotation Apply Mode
The method by which the effectors rotation properties are applied to the clone.
- Add : The effector rotation is weighted by the falloff and added to the clone rotation.
- Multiply : The effector rotation is weighted by the falloff and mutliplied to the clones rotation.
- Replace : The effector rotation is weighted by the falloff and replaces the clones rotation.
Scale Apply Mode
The method by which the effectors scale properties are applied to the clone.
- Add : The effector scale is weighted by the falloff and added to the clone scale.
- Multiply : The effector scale is weighted by the falloff and mutliplied to the clones rotation.
- Replace : The effector scale is weighted by the falloff and replaces the clones rotation.
