FBM Displacement
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 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
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.
