heyas; hmmm... not sure; the last time i imported a poser obj into ray dream and loaded the texture into the colour shader channel, it managed to work right. (go figure! i didnt even know ray dream did uvmapping.) you might try this: export the hair as an obj; open it in uvmapper. select all and place it in one group. then open it in ray dream and apply the shader to the whole thing. or, you can select (in uvmapper) by material and assign them to a group. that way, when you open it in ray dream, the groups will be the materials.
