Normal maps can produce different results in Superfly, Firefly and Preview as the tangent basis in each is different - see this link http://wiki.polycount.com/wiki/Normal_Map_Technical_Details#Tangent_Basis (Superfly uses MikkT which is the most common; Blender is probably using this for baking). Tangent basis is not the same as tangent space, and nothing to do with OpenGL/DirectX either.

Much simpler to use a height map in Poser ;)

Baked normals are really useful for making other maps to use when texturing though, e.g. curvature.

Thanks for the link--good reading--clarified a few things for me.
