I followed the instructions from the Pixologic-site to create a displacement map in ZB3; meaning I ended up with an alpha which I exported. 
The lowresmesh from which I started I imported in Poser7. That only worked out all right if I imported with normals flipped.
Then I applyed the alpha as a displacement map in Poser7. Rendered and some weard things happened with the mesh. It seemed asif the displacement moved into the inside of the mesh.
Maybe that has also to do with the flipped normals?

Can someone who succeeded where I failed help me?
