FieldFractal

The FieldFractal node allows you to apply fractals to fields. For example, FieldNoise followed by FieldFractal will produce Fractal Brownian Motion.

Note:  This is a LABS node, indicated in Nuke with the tag:
LABS nodes are experimental and not intended to be used for production.

Default Value

Function

FieldFractal Tab

Amount

amount

1

Specify the amount of fractals.
Octaves octaves 1 Specify the octaves of the fractals.
Lacunarity lacunarity 2 Specify the lacunarity of the fractals.
Gain gain 0.5 Specify the gain of the fractals.
Display Tab
Draw Bounding Box preview_bounds Unchanged

Draw the bounding box of the field if it has one.

Select between On, Off, and Unchanged. Unchanged means that this option is inherited from nodes above it in the node graph. By inheriting On or Off from above, this means this setting only needs to be edited in one node to affect the display across all Field nodes in the node graph.
Draw Preview preview_on Unchanged

Draw a rough preview of the field.

Select between On, Off, and Unchanged. Unchanged means that this option is inherited from nodes above it in the node graph. By inheriting On or Off from above, this means this setting only needs to be edited in one node to affect the display across all Field nodes in the node graph.
Opacity preview_opacity 1 The opacity at which to draw the preview.
Scale preview_scale 1 A value by which the field is multiplied before drawing. You may need to increase this to display faint volumes for example.
Offset preview_offset 0 A value added to the field before drawing (after scaling).
Detail preview_detail 1 The detail level at which the preview is drawn. Large values are more accurate but slower to draw.
