Blend
Welds the children into a single mesh, with the junction rounded.


Blend treats the children as a single volume and generates a new mesh around them, with the junction rounded instead of a dry intersection. It is like two drops that touch and become one.
Unlike the other modifiers, it does not change each child: it discards the source meshes and produces a new surface, so the topology of the result has no relation to that of the children.
Properties
- Radius: Size of the rounding at the junction. The larger it is, the more the volumes melt into each other.
- Resolution: Density of the generated mesh. High values are expensive, because the calculation is volumetric.
