also, metasequoia has a great metaball toolset. The freeware used to export in obj and I see he has a new version up so I hope that is the same. You can always convert to obj with Crossroads no matter what app you use. http://home.europa.com/~keithr/Crossroads/index.html Also, if you convert, you will want to attach a uvmap to the obj. www.uvmapper.com will do that for you. (so will metasequoia and I think Amorphium)
