If you mean the .pzz or .pz3 file when you say "Poser file", I think I may know why Vue asks you to locate the textures.

I have looked at many of my poser files (created in Poser 6 & 7) in a text editor, and inside all of them, each texture is listed according to the exact path in which it was located when I first created the scene. This obviously includes the drive letter, etc.

So when I transferred my runtimes to a different drive later on, the scene files themselves still had information inside them pointing to the old location of the textures.

To avoid this hassle, I handled it 1 of 2 ways:

1. Before importing the scene into Vue, I made a copy of it (to be safe), opened it in a text editor, and did a "Search and Replace" of all the paths to update the jpgs to their new location. After saving the edited scene, Vue then read those updated texture paths and imported the scene without asking me to locate anything.

(If you don't like editing your scenes in text editors), you can also:

2. Get Poser to export all the textures used in your scene to a single folder, and place the files from that folder in the same directory in which your Vue scene resides.

How do you do this in Poser? Go to the menu, choose --
Scripts, Utility, collectSceneInventory, Copy all to folder

Vue will first look for the textures in their original locations, and when it doesn't find them, it will 'spot' them in their new location (because they are in the same directory as your .vue scene). So Vue will show this message:

"Unable to find file (then it gives the file's original path) --
Use file (mentions the file it found in the copied location) instead?"

Choose "yes to all", and Vue will then automatically use all the other texture files in that same folder.

I prefer method # 1 btw. : )
And I sincerely hope this helps.  ; )

**EDIT: **I need to add that I had to decompress my .pzz files in order to edit them. The .pzz files look like gibberish inside text editors, but the .pz3 files have language I can read!  :p
