There are a number of threads about poor poses from a P7 import into Vue6. There was one yesterday I think in the Poser forum.
I use Poser a lot for import into Vue and currently even though I have P7 I'm still using P6 because of these issues!

I currently use Poser 6 with Vue6Inf same build as yours and there is no pose issues, other issues yes, but not pose ones!

Injustice will be avenged.
