Anim8or doesn't produce UV coordinates by default. However, Poser will produce a textured preview of an un-mapped mesh to confuse you; then when you render, the texture disappears. :( Run your book through UVMapper, apply a map and try again. There's no difference between .obj and .OBJ, but there might be something in these files which Vue doesn't like. If you load it into UVMapper and save again without modifying anything, it may well fix it - UVMapper reads just about anything, but only outputs proper obj format.
