FBM Deformer

FBM Deformer

Deforms the field based on 3D noise.

Method #

This node deforms the field based on a Fractional Brownian Motion algorithm. This allows extra fine detail and animation to be added to already-made field systems without changing the underlying simulation or requiring a higher resolution field.


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.

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.

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.

Displacement AmountHow much the deformer displaces the original mesh.
Noise ScaleScale the size of the generated fractal noise.
Falloff RangeLimits the range the deformer is effective at.
Animation RateSpeed the deformer is animated at.
LacunartiyHow large the gaps between larger areas of noise are.
GainThe overall smoothness of the generated fractal noise.
Update Time ModeHow the field deformer updates with relation to the time code.
  • Locked To Timecode : The deformer deformations are locked to the time code and the same time will always yield the same deformations.
  • Running / Looping : The deformer deformations are disconnected from the time code and will loop seamlessly at the end of the layer.
Upsample DensitiesWhen enabled, the Density field will be double in resolution, but the velocity field remain the same size. This will give much greater clarity to the image, with a smaller impact on performance.
