Poser reads the materials that are listed in the .obj file. Then writes them into the figure's .cr2 file. You can use the MAC version of UVmapper to change the name of the material easy enough. But you'll still have the old material in your list in Poser unless you manually remove it somehow. Us PC users use CR2edit for that. But you could open your .cr2 file with a text editor and remove the materials with that. ScottA
