I did a tutorial to convert mc6 to pose files, here  http://lullystutorials.blogspot.co.uk/search/label/Convert%20.mc6%20to%20.pz2  you probably wont need the additional programme unless you have millions of files to convert and it just saves you a heap of work.

Tools:- Win10, Dell XPS8900, ZBrush, Marvelous Designer 11, Hex 2, PSP8. PSP 2019 Ultimate, DAZ Studio, Affinity Photo, Affinity Designer, Filterforge 11, flowscape,  Classic UVMapper, and several headache tablets.
