It's probably a "normals forward" issue.  We had a similar thread about Angelyna Wings

If  you use Poser 6 or Poser 7, you can easily turn on normals forward in the material room. Just click on the material room tab, and in the large "Poser Surface Node" put a check mark in the box at the bottom that says "normals forward".  Do that for each material zone of the wings.

If you use Poser 5, the method is a bit more complicated in that you have to do it manually instead of just checking a box.  The details of how to do that can be found in the thread above.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
