Hi there, I have found something strange when using 'translate' to move an
object and viewing it using photons. My code is below. Near the end I draw the
'monolayer' shape and translate it by <5,0,0>. However povray returns a black
image. With translate <0,0,0> I get the expected result.

Am I doing something wrong?
Thanks,
Stu
