And here is a trusty little script that will help you with that :)

svdl came to my rescue and made a script to turn on Normals Forward for all material zones at once.

It's for Poser 6.  I don't know  if it will work for Poser 7.  Poser 5 doesn't have a "normals forward" area and you have to do each zone manually using the grouping tool I think.

The working script is the second one posted.

"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
