im looking for man-bot and mentor meshes
For FF1 or 2? You can always unpack your art.ff directory, giving you access to all of the art assets of the game. You can do so by renaming it to art.zip. And unzipping it. Otherwise, you can find Irrational meshes here:

Replace the "1" with 2-5 or 6, and you'll have all of them.
