Open Poser then under the file menu you will find "Convert Hier file..." browse to find the uwings.phi then click ok and it will work. Then save the wings as a character. I found them to be huge and need scaling for most of my character work, especially if you are using my lacy wings texture, so scale them down and move the body of the wings to the proper place on the back of a figure and parent them to the chest before you save the wings. I hope this helps. When I first downloaded them I figured it out from bits and pieces gleaned from lurking around the forums here. Hope this helped.
