I was going to post a tut dealing with making convincing rocks & boulders using metaballs. Now I used Metasequoia for this, although it should be broadly applicable in any software that can do metaballs. But all the tutorial options are tied to specific applications. Can't there be a tutorial option for general 3d modelling (since there's a forum for that, and none for Metasequoia)? Mick ;)
