Hi,
Is there yet any way to pass a custom / photometric light falloff data to POV

-If not, maybe it could be done by entering a spline for the radius/falloff of a
spotlight for artistic effects (this is also good for integration with Blender's
interface, I could then use Blender custom curve or create that curve frome ies
files directly in Blender exporter)?


-Or, maybe it's planned for POV to simply support ies and ldt files provided by
lamp manufacturers?


The most recent information I could find about these are :

- This old Dialux patch :

- And this "more recent" (2008) one by delle:
