Fbm Deformer

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.

Transform

Name Description
Position X Move its position along the x-axis in local space.
Position Y Move its position along the y-axis in local space.
Position Z Move its position along the z-axis in local space.
Rotation Heading Rotate the object about the y-axis.
Rotation Pitch Rotate the object about the x-axis.
Rotation Bank Rotate the object about the z-axis.
Scale X Scale along the x-axis.
Scale Y Scale along the y-axis.
Scale Z Scale along the z-axis.

Inherit Transform Channels

Toggle which transform channels should be inherited. By default, all are on.

Attributes

Name Description
Displacement Amount How much the deformer displaces the original mesh.
Noise Scale Scale the size of any noise generated.
Falloff Range Limits the range the deformer is effective at.
Animation Rate Speed the deformer is animated at.
Lacunartiy How large the gaps between the generated noise is.
Gain The smoothness of the generated noise.
Update Time Mode How the 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 Densities When 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.
