Why do you want to use a pose file? What benefit do you hope to achieve by doing it with a pose file?

My goal is to reuse common parts.  For example, buttons of the clothing.  It is an experiment to see if I can have some "static" objects attached to clothing.  If it works, I can make some fantasy armor pieces with some complicated decorations.

The pose file will be used to position these "static" objects.  For example, the bikini set cr2 will not really contain any bow.  The bows will be loaded from a separated cr2 and placed by the pose file.  I'm not sure if it is a good idea or not.
