Are you aware that POV-Ray promotes
the 0.00003 scalar in your
"translate 0.00003" expression to a
vector, so that the expression
becomes this:

translate <0.00003, 0.00003, 0.00003>
?

Maybe you meant to write:

translate 0.00003*y
?

Hmmm...
I see now that you are using Moray.
Maybe I haven't found your problem.
