I still like using the free modeler that Metasequoia puts out. Great metaball tools. You can do a lot for the price. Get the freeware one, it has most of the same features and it exports in formats that Bryce likes. The shareware is kewl too, but doesn't export, only saves in native format (which the freeware reads). I've got a tut up with the links. http://www.annsartgallery.com/donut.html
