Josh has said b3d export will be back in version 5 of CartShop.
I was using CartShop over Quill3D because my levels were very high poly and Quill3D was struggling.
Now however my levels are alot lower poly count and since Quill3D has caulk faces and clipping to a plane it is much easier for me to design my levels with it.
Both Quill3D and CartShop have their share of bugs but spending ?000's on Max has never been an option for me.
So for now I use Quill3D and Gile[s] to get a correctly exported and lightmapped .b3d file.
