Generates a volumetric shape in the grid, with 0 value on the surface, positive values increasing into the center and negative values extending outwards.

*Shape*: Shape of the volume being generated. If plane is chosen, additional options are displayed for what axis to use.

*Center*: Centerpoint for the shape to generate on. The point is in object space unless world space is ticked on.

*Size*: Shape is generated inside a sphere of radius size.

*Scale*: Scalar value for each axis.

*Positive Density*: Multiplier for the positive density values.

*Negative Density*: Multiplier for the negative density values.

*Positive Add*: Value added to the positive side after multiplication.

*Negative Add*: Value added to the negative side after multiplication.

*Operation*: Method by which the effect is blended with the existing density value.

*Mix*: Dissolve between the original image at 0 and the full effect at 1.
