ive tried selecting most of the edges but none of them have corresponding ones? Heres what i'm doing :-

Right click > Select faces, hold the left button and drag over the whole area i want to uv map, > view selected then i >Edit polygons > Texture > Automatic uv mapping.

Do the settings in the automtic uv mapping menu have to be set in any particular way, on mine its on its default setting.

Thanks for any help
