I was browsing galleries and saw some work buy a guy named Englewolf. It looks like he's using negative boolean unions with metaballs but I cant get bryce to do that. does anyone have any idea how he's getting such smooth organic shapes in bryce?

I tried asking him but it seems my email addy in my profile was outdated so if i got a response it never made it to me.
