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.
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.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z 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.
These properties control the core behaviours of the node.
Parameter Details
Displacement Amount How much the deformer displaces the original mesh.
Noise Scale Scale the size of the generated fractal noise.
Falloff Range Limits the range the deformer is effective at.
Animation Rate Speed the deformer is animated at.
Lacunartiy How large the gaps between larger areas of noise are.
Gain The overall smoothness of the generated fractal noise.
Update Time Mode How 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 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.
