As you can see, certain faces are not being textured, despite the map covering them. On the UV view there are vertexes which are unselected, but selecting them manually makes no difference - they are unselected as a result of an unmapping, and I suspect the issue is linked to those vertexes, although deleting them and remaking them only makes the problem worse. Please note, the textures are not invisible, but white, so I know the normals are all fine (I checked them anyway, and they are all the correct way round). There are no doubles either. I'm genuinely stumped by this. Any help would be greatly appreciated. Thankyou.
