Sorry, I just discovered a bug I added in the version 1.0 of the plug-in when I copied the code contributed by fma: I shifted months value, because months in GregorianCalendar class are 0 based.
Therefore, I released the new version:
http://www.sweethome3d.eu/plugins/AdvancedRendering-1.1.sh3p
and removed links to the older version 1.0.
As plug-ins management automatically choses the most recent version of a same plug-in available under two different versions, you won't be obliged to remove version 1.0 after installing the new version.
