Problem whit rendering scene with a light source

The suggestion with pfilt=-a did work. Thank you Ignacio very much. Thank
you also Greg for the theoritical backround.

This is the error you get when your picture contains nothing but zero
pixels. See earlier responses to your queries as to why.

Hello list,

I am trying to simulate a scene of light source behind a glass. The image
is part of a general simulation.

When I am trying to simulate the results are the following:

pfilt: picture too dark or too bright
rad: error filtering view sun
        lab_6i2_sun.pic removed

If you have any idea, it would be highly appreciated

Thank you

Sotiris Papantoniou

P.S. I am sending the files of the simulation to help.
