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.

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 | off | Draw the bounding box of the field if it has one. |
| Draw Preview | preview_on | off | Draw a rough preview of the field. |
| Preview 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. |
