Import .OBJ and UV mapping

[orbiter]

I have a model created in wings, this was then exported as an .obj to allow some work on the exact placing of the uv and then RE-imported as an .obj.

The model imports fine, When I open the UV editor It has the "neater" / new UV map. So I save this as a texture, make external as a .PNG file and modify the texture with the image I wish to be painted on to the vertices. This is then brought back into wings with the refresh command and I can see the auvBG thumbnail image change.

However it is not applied the the surface of the model. When I select the model and UV map, a new texture is drawn complete with the ABCD checkerboard. I new auvBG image is added to the outliner window list.

The Materials do not pick up the texture file name. I just end up going round in circles.

Any help really welcome folks
