Fractal Noise
Updated: 9 Sep 2025
Generates various fractal noises.Updated: 9 Sep 2025
Generates various fractal noises.This node generates fractal noise using various methods for a shading system. Useful for adding randomness and variation to a surface or volume.
The output of this node is a shader, which can either be combined with other Shading nodes for more complex designs, or applied to Materials to directly control one of the material channels. They can also be applied to Fields, where they can be used on the various channels on the Field Emitters to control how the smoke is generated, and Field Materials to control how the field is rendered.
These properties control the core behaviours of the node.
Parameter | Details |
---|---|
Mapping Type |
How the generated shader is applied to the surface.
|
Noise Type |
Select the noise function to generate noise from.
|
Threshold | Shift the minimum value for the fractal noise gradient. |
Ramp Power | Change how the gradient changes between the high and low values. |
Noise Scale | Scale the size of any noise generated. |
Offset Amount | For warping fractal noises, controls how much the fractal noise is offset by the warp. |
Num Octaves | How many times the noise generation is iterated at different noise levels. |
Preview In Viewport | Preview the effects of the shading node on the channel it’s applied, without other nodes further in the chain being used. |
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 shader’s position along the local x-axis. |
Position Y | The shader’s position along the local y-axis. |
Position Z | The shader’s position along the local z-axis. |
Rotation Heading | The shader’s rotation around the local y-axis. |
Rotation Pitch | The shader’s rotation around the local x-axis. |
Rotation Bank | The shader’s rotation around the local z-axis. |
Scale X | The shader’s scale along the local x-axis. |
Scale Y | The shader’s scale along the local y-axis. |
Scale Z | The shader’s 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. |
