Base Model modification issue

[nomorecookies]

Hello. I have successfully altered the position of the helper cubes of the base model by using the .OBJ from the source code. I have successfully exported it from Blender as .OBJ and then converted it to .npz. It works as expected when i replace the base model with it, targets and all. The one problem i am having is when i try to export to MHX using the modified model within MH, it will not export. It thinks it exported, but it does not write the file.

So, my question is, what are the proper blender .obj export settings, and is there a trick i am missing?

Thank you
