FieldWarp
The FieldWarp node warps a field according to a second, warp field. There are two modes: Absolute and Relative. In Absolute mode, the warp field should return the new position for each point in space. In Relative mode it should return a vector indicating how far to move each point. There is also an Auto mode which will choose between Absolute or Relative depending on the type of field.
Nodes which produce fields suitable for the warp input include: FieldTransform, FieldDeform, and FieldNoise.
Note: This is a LABS node, indicated in Nuke with the tag: 
LABS nodes are experimental and not intended to be used for production.

| 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. |
