The "magnetic field" of influence is defined by a metaball field.
This node is a simpler version of the Magnet node.
Click the Bulge tool on the Deform tab.
Select the geometry to deform and press Enter to confirm your selection.
The bulge will be more visible if your geometry has a lot of detail.
Select the magnet metaballs and press Enter to confirm your selection.
Increase or decrease the Magnitude in the parameter editor to create a bulge.
Click the metaball transform object node in the network editor to move the metaballs under the surface of the geometry.
If the metaballs are peaking through the surface of the geometry, adjust them so they merely bulge slightly against the surface.
Geometry to be deformed with the magnet.
Magnet primitives in the 2nd input.
Deform Group Type
The type of geometry to deform.
Scaling factor for point displacement.
Normalize the displacement vector from the metaball origin to the point.
Create a simple cat head by using the Bulge SOP combined with metaballs and a NURBS sphere.
The Bulge SOP is used to deform geometry using a metaball as a magnet force.
The magnitude of the magnet force can be adusted in the Bulge SOP.
The parameters in the Metaball SOP may also be adjusted to modify the final effect of the Bulge SOP on the deforming geometry.
