I use Blender 2.70 on a Mac. My question is if it is possible to have a metaball with a different shape.
As I know metaballs are typically cubes or spheres. But I need some kind of cylinder or egg or random shape.
You can place a meatball into Edit mode. This will present you with a couple of extra parameters under the N-KEY panel that shows up along the right-side of the viewport. The Radius parameter only shows up in this panel and not in the data block view (as it should IMHO).
