[Radiance-general] rcontrib for rendering - missing required modifier argument

[Greg Ward]

Hi Urtza,

You should not be using the file "klems_ang.cal" but something like "klems_full.cal" or klems_int.cal.  This is why Nkbins was undefined, and probably at least one reason your simulation is not working.

Best,
-Greg
