I am also an MD2 user and I really love the program. It is very intuitive to use, even for someone with no experience in sewing clothing. It is also easy enough to use your own avatar and poses, and get everything in the render program you want to use it in.  I have no problem with the way I work with the program, although it might sound pretty tedious. But exporting and importing between Daz studio, MD2 and Vue esprit goes so quickly that I have no issue with it.

Just to give an idea of how I work with MD2: I will start with exporting a T-posed character, then load that into MD2 as the avatar, make the clothing I want and texture it. Then I go back to Daz Studio and pose my character + export it. Import the pose in MD2 and watch the avatar move into the new pose, while the clothing drapes with the new pose. Then I export the finished draped clothing and import it into Daz Studio on the character I saved from before. And then I export to Vue esprit. Works fine for me, and once you got an T-pose saved for one character you can reuse that T-pose for any new clothing you want to make for the character.

Certainly saves me from buying clothing for my 3D people, plus I can use any morphs on my characters, the clothing will always fit. :)
