Once you have placed your library items in the proper library and in the array you like, you need to make sure those items can find the textures they need and quickly. Poser5 is very cranky about finding textures. To maintain your texture library it is necessary to run CorrectReference on each library item requiring a text (hair, characters, props, and MAT pose files). CorrectReference is a free utility available here. Each time you load one of these items, use the utility. Each time you move a texture, use it also.
