FBM Displacement
Updated: 4 Dec 2023
Apply FBM deformation to a procedural.
FBM Displacement
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.
Parameter Details Position X
The objects position along the local x-axis.
Position Y
The objects position along the local y-axis.
Position Z
The objects position along the local z-axis.
Rotation Heading
The objects rotation around the local y-axis.
Rotation Pitch
The objects rotation around the local x-axis.
Rotation Bank
The objects rotation around the local z-axis.
Scale X
The objects scale along the local x-axis.
Scale Y
The objects scale along the local y-axis.
Scale Z
The objects 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.
These properties control the core behaviours of the node.
Parameter Details Num Octaves
How many time the noise generation is iterated.
Noise Scale
Scale the size of the generated fractal noise.
Amplitude
How greatly the generated noise adds to the distance field.
Lacunarity
How large the gaps between larger areas of noise are.
Gain
The overall smoothness of the generated fractal noise.
Colour 0
If the renderer in the procedural network produces colour then this colour will be used for the displaced shape.
Colour 1
If the renderer in the procedural network produces colour then this colour will be used for the displaced shape.
Apply Mode
How 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.
