In addition to having several meta objects in a same family, you can also have several meta primitives in a single object (just add some more while in Edit Mode). Each will be an element, with its own shape, editing rings (in the viewport), and settings.

X, Delete

You can only delete the active element, no fancy options here.


To convert the meta to a real mesh, use Converter in Object Mode.

Família de objetos

Uma «família» é uma maneira de reagrupar diversos objetos de esfera-meta, produzindo algo bem similar ao que seria correspondente a ter diversos objetos de esfera-meta dentro do mesmo objeto.

It is defined by the left part of an object’s name (the one before the first dot). Remember, an object’s name is the one in the Object Name field, in most panels, not the Metaball Name field, which is the meta data-block’s name… For example, the family part of «MetaPlane.001» is MetaPlane. Each meta object in the same «family» is associated with one another as discussed below.


Metaball family.

Families of metas are controlled by a base meta object which is identified by an object name without a dot in it. For example, if we have three metas called MetaThing, MetaThing.001, MetaThing.round, the base meta object would be MetaThing.

The base meta object determines the basis, the resolution, the threshold, and the transformations. It also has the material and texture area. In a way, the base meta is the «owner» of the other metas in the family (i.e. it is as if the other metas were «included» or joined into the base one).


Ao trabalhar com múltiplas cenas, tome o cuidado de nomear corretamente os seus objetos de esfera-meta de maneira que o objeto marcado como base esteja sempre dentro da mesma cena que os outros objetos de esfera-meta vinculados por familiaridade.

Failing to do so will give confusing behaviors (like invisible meta objects).


Fig. Base das esferas-meta. shows the base meta labeled «B». The other two Meta objects are children. Children’s selection rings are always black, while the group’s mesh is orange. Because the metas are grouped, they form a unified mesh which can always be selected by selecting the mesh of any meta in the group.


Base das esferas-meta.

For example, in Fig. Base das esferas-meta., only the lower sphere (the parent) has been selected, and you see that both the parent’s mesh and all of the children’s meshes are now highlighted.


Escalonando a «base».

O objeto definido como base da família de esferas-meta controla a poligonização (estrutura da malha) para o grupo, e portanto, também controla a «poligonização» para as outras esferas-meta crianças (objetos não-base pertencentes a mesma família). Caso façamos transformações na esfera-meta usada como base, a poligonização dos objetos criança será alterada. Contudo, caso façamos alterações de transformação nas crianças, a poligonização permanecerá inalterada.


This discussion of «polygonalization» does not mean that the various meshes do not deform towards or away from each other (meta objects always influence one another in the usual way, within a same family).

Rather, it means that the underlying mesh structure changes only when the base object transforms. For example, if you scale the base, the children’s mesh structure changes.

In Fig. Escalonando a «base»., the base has been scaled down, which has the effect of scaling the mesh structure of each of the children. As you can see, the children’s mesh resolution has increased, while the base decreased. The children did not change size!
