I'm not entirely certain I know what you mean by "Model the whole thing"... but
I don't have Wings3D, and I really don't use anything but POV.  I've tried
creating the object as an Isosurface with cracks made using a crackle pattern,
but the cracks propagate straight through along an axis, rather than down from
the surface.

I think that what I need is a high-definition height map, with the crack drawn
in.  Something that I can wrap around a sphere...

At least that way, I'll be able to handle impact craters at the same time.
