Yet another import question

OK we are having issues with exporting as FBX and importing Maya scene files .mb.The model comes across fine but the textures dont update when imported.
We have tried putting the fbx and maya scene file in the same textures folder and drag them into unity. in no instance does the textures appear on the model we have to asign them eveytime.

So the question is what is preventing the texture to import onto model during import?

Many thanks

Texture import is explain here: http://unity3d.com/support/documentation/Manual/Meshes.html quite well. Have to checked it out? If it still doesn’t work, could you post a minimal project with your model and textures which reproduce the issue?
