Yes, Twoface is what I should have said :-((. Cybermonk shows a lot more experience with fixing normals than I have :-)) - If you have a choice in mesh types, I always prefer OBJ format - I don't think Poser even imports RayDream files directly. You'd need an external program to convert. If it's only avail in RDS or another incompatible format, check out 3D Exploration (shareware, available from Right Hemisphere - Has a great browser-type preview screen, & converts between several 3D formats. I've heard of another called (I think?) Crossroads, that converts, but I have no experience with it, as I came across 3D Exploration first, & it does nearly everything I needed (A bit Pricey to register, though). Good Luck!
