nope, this Obj ain't closed.
so often that is the solution, yes, but not in this case unfortunately.
i did test-run ABF on some other stuff, but on complex geometry it fails, while PLG runs smoothly.
seems to be an ABF thing. i believe also that this is the first version of ABF, and not ABF++
not criminally bad, but not ideal either. PLG saves the day in this case.
Looking into Rizom also by the way, seems close to Magic.
i should add, the geometry for this object is not ideal, at all.
don't blame me, i didn't model it....
