I believe that I replied to the email that you sent me earlier regarding this issue. In it I was asking for more information and possibly screen shots to illustrate the problem. You replied saying that when you selected the dress the IK menu option was grayed out. I indicated that, yes, that would be the case if no IK's were present in the dress.

I'm very happy to continue to help but currently I'm still in the position of requiring more information.

Could you please supply screen shots?
Would you be able to send me a copy of the dress CR2 and OBJ files?
What version of Poser are you using?

Thanks.
