Glad that was the solution :)

Here is a script for Poser 6 that allows you to turn on normals forward for all material zones in the scene with just the click of a button.

I usually turn it on regardless of whether it's needed or not.

"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
