FieldInvert

The FieldInvert node inverts a field. The meaning of "invert" depends on the type of input field. For a signed distance field, it means to negate the field values (so that the inside and outside of the shape are swapped). For other types, it means to subtract the field values from 1.

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.
