You would be shocked at what a mess I've made of the lighting and texturing in
the scene that this came from so yes the finish would need a lot of fixing. I've
always had trouble with that part of POV-Ray...

Ten layers is much more reasonable than a hundred and your excellent results
prove it. I admit that a hundred layers is a bit of overkill. (Sometimes I tend
to be a bit of a perfectionist. I don't quite have OCD, but I do have CDO which
is similar, but with the letters in alphabetical order like they're supposed to
be.)

I've been using this sample image as a Granite_21 reference point:

This one represents near perfection in my opinion (the color samples I used came
from that picture, by the way). But I agree, both methods produce great results
and I'm more excited than ever regarding Granite_21. Thanks for sharing your
preliminary results!

Kind regards,
