can Cshop4 export to b3d??
Not the version I have. 4.1 was supposed to be out a while back, but I haven't heard anything, and now Josh is away, like IPete2 said.
If I were you, I wouldn't buy CShop until 4.1 comes along because the whole 4.x release has been done extremely badly in my opinion. CSG was pulled out because Josh couldn't get it working, and we're probably still waiting for bugs in the CSG to be fixed so that 4.1 can be released. I haven't seen any sign of an importer for CSM 4 files, and there's no B3d export. Looking past all that, I made a test level to see how it was going, and there are problems with the UV mapping as well. Lots of areas of a very simple map just didn't line up any more, whereas they would have done in CS3.
If Josh can take care of all the problems, it would be a far better choice than Quill, in my opinion, but it's worth hanging on to see if he does.
