Someone in the Poser Tech forum was also having trouble with center points returning to zero. You may want to take a look at this thread: http://www.renderosity.com/messages.ez?ForumID=10139&Form.ShowMessage=282726

I've never seen this happen before, but if two people are experiencing the same problem then it might be helpful to compare your set-ups and see where this problem might be stemming from.

It's been a long time since I've used RDS, but if you have the .obj plugin it shouldn't be too difficult to import into Poser.
