Hi all,

I am a new user of Pov-Ray, and I had this error. I have the .pov file generated
from the other program, but when I try to render it in POV-Ray, I get the error:
"Parse Error: Expected 'numeric expression', undeclared identifier 'nan' found
instead". Did anybody solve this issue already? Thank you a lot in advance.

Best,
Hanna

just a "shot in the dark", but could it be that the generating program, for some
reason, cannot compute some value and outputs a "Not a Number" result ?  it
might help if you could post the scene, or the relevant bits from it.

Thank you a lot for the reply! Indeed, the problem was with the files generated
via external program, so not related to POV-Ray.

Thank you again,
Best wishes,
Hanna
