Ahh, I see.

Normals are calculated by Wings 3D so they may be wrong when converted to .pov
format (or just plain wrong in Wings 3D full stop).

The images have loads of space as that was the way Wings 3D set it up (e.g. gave
me the outline for the 6 sides of the cubes and I filled them in with the
appropriate textures). It is only a test anyway. Once I get the hang of it I
will minimize space wastage ;)

Thanks. I have it working as desired now, and can continue to create more models
and images using Wings 3D and POV-Ray :)
