Blender UV map not importing correctly

Hi everyone,

I've gone back to a project that I've not touched for quite some time, since a 3D model got corrupted in it after (I think) the Unity 3.5 update.

I've sorted out the model, done the UV mapping in Blender and as you can see from the screenshot, it's fine in Blender.

However, when I import it to Unity the UV mapping doesn't seem to import correctly and it's all over the place. I've tried swapping UVs on the import settings and that doesn't improve the situation. I can't even work out the UV map from the material - it seems the head, for example, is a zero-point UV space.

Does anyone have any advice or are experiencing similar problems?

Any help would be appreciated!
