FieldNoise

The FieldNoise node generates a field containing Perlin noise. It can produce 1, 2, or 3 dimensions of 4D Perlin noise. Three dimension are useful for random colors or forces. One dimension is useful for random densities or to modulate other fields.

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

Inputs and Controls

Connection Type	Connection Name	Function
No inputs.

Control (UI)	Knob (Scripting)	Default Value	Function
FieldNoise Tab
Noise Type	mode	Perlin	Specify the type of noise to apply - Perlin or Random.
Dimensions	dimensions	3D	Specify the dimensions for the noise to be applied.
Amount	amount	x=1, y=1, z=1	Specify the amount of noise to apply.
Time	time	0	Specify the time for the noise.
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	0.5	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.
