Not sure if I follow you, but it sounds like you think Poser will save the Texture info to the Pose library. If so, that is incorrect. You can not make a MAT pose file by saving a figure to the library. Poser will save only certain information to the library in way of a pose file. This is basically the dial setting infor for the element body part groups but NOT for the Body group (Full Body MORPH dial info, ERC dial info, etc., does not save to the pose library). Scale info (x, y, z scale dials) also does not save. To make a MAT pose file or to save this other information not normally saved by Poser to the library (such as FBM settings) you have to make a special Pose file using either a utility program that is set up to do this or else manually using a text editor and making the pose file by hand.
