Well, I;m not sure about cut and pasteing texture maps. Normally you "load" them (open them) to a material. The Poser 5 manual explains how to go about this. Otherwords you need to save the map from photoshop as a jpeg, or other image file and then load it. This way Poser has a "real" image file to use. At time of rendering it loads this image and renders it however it is mapped to 3D object. It really needs an actual image file.
