I assume you are trying to apply the texture via a pz2. Here are some things you need to know about applying pz2 (pose) files to props. A pose file will only work when there is a figure in the scene. A number is appended to a prop when it is loaded in Poser, the first instance loaded will be "propName_1", the second instance "propName_2", etc. The name in the pz2 must match exactly the name of the prop, including its number. To apply a pose to a prop that is  NOT parented to a figure you must use "actor propName_1" not "prop propName_1" in the pz2.
