Colour Ramp Effector
Updated: 4 Dec 2023
Modifies a cloner system with colours from an input Colour Ramp.
Colour Ramp Effector
Method #
This node primarily modifies the colour values of connected cloner systems based on an input Colour Ramp, but can also apply transformations to the clones too based on the area of effect of the colour ramp.
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.

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.
- Object : Use the transforms in object space to influence the clones.
Colour Blend Mode
How the colour blends with other colour data.
Colour Blend Amount
How much the colour blends with the original clones colour.
Source Channel
What property of the clones in relation to the effector should be used to dictate colour.
- Position X : Clones are coloured based on their X position.
- Position Y : Clones are coloured based on their Y position.
- Position Z : Clones are coloured based on their Z position.
- Distance : Clones are coloured based on their radial distance from the effector.
- Fractal Noise : Clones will be coloured based on a simple fractal noise function.
- Clone Index : Clones will be coloured based on their index.
- Random Value : Clones are coloured completely randomly with the input colour ramp.
Source Scale
Scale the size of the source Colour Ramp.
Source Offset
Offset the values from the source Colour Ramp.
Modulate Function
The method by which the colour ramp is sampled / repeated.
- Clamp : The sample locations are clamped from 0 to 1.
- Repeat : The sample locations are repeated.
- Sine : The sample locations are modulated with a sine wave.
Interpolate Colours
Allow the clones to interpolate the colours passed to them, smoothing the colour changes across the clones.
Noise Scale
Scale the size of the generated fractal noise. Only functions with Fractal Noise selected in the Source Channel Attribute.
Lacunarity
How large the gaps between larger areas of noise are. Only functions with Fractal Noise selected in the Source Channel Attribute.
Gain

Animation Rate
The speed at which the fractal noise is animated. Only functions with Fractal Noise selected in the Source Channel Attribute.
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.
These properties control where an effector can affect the clones.
Parameter Details Falloff Mode

- 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
