Render Subdivision
Denes the number of subdivisions that are rendered. The subdivision is specied in distance units.
This means that you should lower the value to increase the number of subdivisions and mesh-
smoothness. Increasing the value will reduce the number of subdivisions. You should choose a low
setting here (e.g. 5), so that the surface is rendered smoothly.
Exponential Falloff
By default, the force of attraction of metaball spheres to each other is similar to gravity, which has a
1/r^2 relation. You can change this with the Exponential Falloff which, if enabled, has the effect that
metaball attraction occurs at shorter distances, and more abruptly.
Metaball Tag
You can assign a metaball tag to child objects of the metaball for further control. In the Object manager,
select the child object that you want to ne-tune and choose File > CINEMA 4D Tags > Metaball. The
tag is added to the object and the tag’s settings are displayed in the Attribute manager.
Negative Inuence
Normally, objects attract the metaball hull and make it expand. However, if you activate this option,
the object will repel the hull instead and cause it to shrink.
Strength
You can use Strength to dene how strongly the object affects the hull relative to the other objects.
Radius
This value determines the radius used by the object to affect the hull. The Radius parameter has no
effect on metaball spheres.
