I found this modeller is quite interesting
www.artofillusion.org
Does it export .x or 3ds? I can't find it on the site.
AoI only exports OBJ, POV and VRML and imports OBJ only, so it's not a one-step solution. In concert with UU3D or Milkshape, it's a great tool, especially for its Boolean modeling capabilities.
coulda swore someone posted AoL links here a while back. pretty sure that's how i knew of it.
we should have a sticky with links.
