Method #

This node applies an FBM (Fractal Brownian Motion) deformation to the procedural. Useful for adding noise to a surface or cloud.

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 XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Num OctavesHow many time the noise generation is iterated.
Noise ScaleScale the size of the generated fractal noise.
AmplitudeHow greatly the generated noise adds to the distance field.
LacunarityHow large the gaps between larger areas of noise are.
GainThe overall smoothness of the generated fractal noise.
Colour 0If the renderer in the procedural network produces colour then this colour will be used for the displaced shape.
Colour 1If the renderer in the procedural network produces colour then this colour will be used for the displaced shape.
Apply ModeHow the displacement will be applied to the distance field.
  • Add : Add to the current distance field.
  • Subtract : Subtract from the distance field.
  • Add Signed : Only add to the distance field when the fbm displacement is positive.
