I don't know about that, sorry.

What I do know is that you need File Search set to 'Deep' (in Preferences) to make Poser look in all Runtimes. (Did you check that setting?)

or
 
You must make sure that all your references to texture files within the material that you are loading are full and correct file paths. If you check the file paths for the image maps inside your shader files (using a text editor) it might show up where the problem is.

Otherwise I'm completely lost on this problem. :O)
