I am amazed you are considering tackling it at all. It must be a nightmare. (My
developer days are over, I'm afraid - it was all beginning to make my brain hurt
a bit too much). (And thanks for the tip on subdivision. I will try that out,
though I think I gave it a go some time back and had problems still.)

To be honest I have tried various settings with subsurface and found it way over
the top, artifact city or no appreciable effect at all (but, as I said above,
this was some time ago. Perhaps if I revisit the problem with renewed vigour and
a smaller mesh?)

I think the most frustrating thing, though, is the time it takes to render. I
set a render in motion, go away, return ten years later and bang my head on the
table because something is still not right in the image. Which is why I am
following the cheating path as it makes me feel a lot less like Sisyphus.

Has anybody else used the Samuel Benge (thank you Samuel, btw) fastprox macros,
and had satisfaction, do you know? Is this a route worthy of further travail?
