In reference to the files linked...

There is no obj file provided which is called by the cr2, nor is there embedded geometry in the cr2 (geomCustom).

The Blend file provided promptly crashes Blender, so no way to export the obj from there in order to correct the cr2 call.

Curiously enough the rig appears to be Poser compliant in terms of classic bones internal names/body part groups conventions. Just going by the screen captures, and seeing the naming and Hierarchies.

I would try manually posing the figure and testing the results, you're attempting to apply a La Femme pose to this figure... the body part bones are different between the two. Notably the feet, this (very) partially explains the problems you're encountering there. The rig is also going to require quite a bit of joint editor work before you'll get something to even begin fine tuning. Not to mention the lack of head parts such as rigged eyes, and assuming jaw parts. You'll have to do quite a bit of work in the set up room. There's no automated solution here, at least not in my opinion, in order to get a reasonably viable Poser figure from the rig's current state. It's kind of a subjective thing, what's "good enough"...

It's a lot of work to be coming at blind. A lot. It's also quite an undertaking to explain such things on the part of whoever would undertake such a task, assuming anyone knowledgeable enough stepped forward to do so. Most of the folks you'll find hereabouts are either not knowledgeable enough about these particular aspects of Poser, or the ones who are just aren't interested or too busy to hand hold in such a fashion. It least to the extent that OP would require.

All that rambling aside, there's also the issue of OP language differences, I believe that OP speaks primarily Japanese... so there might be some confusion or translation issues in trying to explain stuff in a way that would be clear.

Just my 2 cents, for now.
