swift- thanks very much for that detailed response.
I'm intrigued by the idea of using a cubic environment map to set the required vertex colours (tangents). Is a cubic environment map just a cube (6 sided) map? Could you please try to explain this to me one more time as I'm not sure I wholly understand it. Why is a cubic map needed?
