Thanks for your speedy reply Stephen - but I followed your guidance to the
letter and got a reasonable result, especially when I cranked up the ambient to
1,1,1 and diffuse to 1.  Not sure I fully understand the detail of the code but
thats why I use Moray.

But your solution works which is what matters, and for that I'm grateful.

Now going to post another very fundamental question on reflection.
