Pyroclastic Displacement
Updated: 4 Dec 2023
Add blobby noise to a procedural.
Pyroclastic Displacement
Method #
Applies a noise-based deformation to a procedural. The noise generated forms a dense fusion of blobs.
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 octaves of noise are generated.
Noise Scale
Size of the noise generated.
Amplitude
How greatly the generated noise displaces the distance field.
Blob Size
Controls the overall ‘blobiness’ of the displacement.
Animation Rate
When not zero, this property will control how fast the noise animates.
Colour 0
If the renderer of the procedural generates colours, then this colour will be used for the deformed shape.
Colour 1
If the renderer of the procedural generates colours, then this colour will be used for the deformed shape.
