  • Offset: Offsets the surface of the shape. Positive values expand the shape and negative values contract it. This is equivalent to the `round` operator.
  • Thickness: For surface-based fields, this is the thickness of the area where the value is 1.
  • Blending: The distance over which the 1 area transitions to the 0 area.
