@pinkbrainme i split your question and made a thread for you, dont ask things in a thread what has nothing to do with your question
made next time a thread yourself and in the right forum
you can unlink the boxes in Blender but what has that to do with the body and you cant upload or import a box as well you will never have the script
you cant upload a xml file you must import that, but Mesh bodys, objects, etc will stay as box, you have nothing on it,
the only thing you can do, is use Meshes Helper there you make the body rigged, but then the next problem the uploading
and you cant, yes you must have payment used
