Quote - Hm.. maybe I'm behind the times.  I'm using P5, so there's no "normal forward", no advanced tab at all for that matter.

Unfortunately with Poser 5 you have to do normals forward manually, here are instructions courtesy of randym77 who posted these instructions to me a couple of years ago.

Quote - To reverse the normals, use the grouping tool. You will have to do it for each existing group. Select a group, click "reverse normals," then select the next group and repeat until you've done all the groups. Test it by rendering; you'll probably see if you've missed any groups. Save the wings to your library, and you'll never have to do it again. They'll take the same textures and poses as the original wings.

Here's the grouping tool in P5 (it's similar in P6). It's that button with the dotted box. The group you select will turn red, the rest will be dark.

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
