Quote - No, I have to modify the mesh (adding vertices, welding, etc). Because of this I bought Poser 7. I have to detach. But not sure if I can reatach it to the skeleton again. I have no idea if I can save the skeleton, export mesh only and get it back.

Normally this is not a problem, but it gets much easier, if you arrange your cr2 file without any embedded geometry (ie use the 'figureResFile my.obj" in the the cr2). Then you can overwrite the obj with your modeling app to your heart's content (you have to reload the character in poser, though). Only thing to remember is to assign an appropriate group to vertices you add in your modeler. And this does not work with morphs, only for the skeleton, so better save morphs for last.
