If you are going to use NormalMaps I would encourage you to create and use them with TangentSpace.

Hope this helps

Yeah, I read the Poser Pro normal pdf file.
The normal map tests I've done in Poser Pro (zBrush) have resulted in "bumps" that were seemingly largely inverted. I don't know if that's because of Poser, or because I passed the object through LW first and on to ZB as OBJ.
I use "Maya Tangent Space" for LW though - seems to yield the best results.
