Thanks guys, I appreciate the feedback. As I said, I went right back to basics
with everything.

And it isn't that time is an issue - though it does result in hair loss when a
24 hour render reveals itself to be a complete mess - I just feel there must be
a better way to get good results without ramping everything up to the max.

I must confess that I haven't played with albedo too much, but blurred
reflections? I thought that was Uberpov? Or is there a cunning technique for
bulk standard pov?

Cheers

Simon.

PS. Thomas, that is exactly the idea. High reflectivity to confuse the enemy. I
shall tinker. This was only a first draft.
