A partial work around for the B4 people would be to metaball in another program and import it to bryce as a model. For PC users, the freeware Metasequoia has a heck of a decent "blobby" tool which does positive and negative metaballs in any of the primitive shapes. I don't know of any mac freeware modelers that do metaballs though. Since Metasequoia is relatively undocumented i'll work on getting a tut up this weekend on metaballs.
