THIS IS BRILLIANT!!!  (caps intended, since I was shouting)

I loaded Blender 2.61, loaded the add-on, saved as default.  Loaded V4, added Lana Elite Material, render and BAM!  V4 rendered via Blender.  Never been this easy!

I did try making a new CR2 from a posed V4, and she still comes in as default Pose.

Is the Pose section of the directory browser for figure poses, like posing V4? 

With conforming clothes following the poses, are you thinking more of supporting only  dynamic clothes saved as figures, or are you going to try and tackle that?

...but again, great work so far!!!!

Now that I am reloaded on W7/64 with Blender 2.61, I can also help test things if you like.
