nessun problema.  (Google Translate tells me :-))

no, alas.  no warnings/errors is the result of (what I consider) bugs in the
POV-Ray parser.  see this example from the reference page:

    finish { reflection {1.0} ambient 0 diffuse 0 }

your code is missing the braces required by 'reflection'.

yes, sorry.  WFP = William F Pokorny, he's the author of 'yuqk', a branch/fork
from the POV-Ray 3.8 line.  see, for example, the following thread:
<news.povray.org/povray.binaries.programming/thread/%3C68258118%241%40news.povray.org%3E/>

(and his parser is stricter than POV-Ray's, enforcing the 'reflection {}'
syntax)



regards, jr.
