Thanks! I just read in the POV docs about the no_image keyword, because it
seems strange to me that this should work any different than having a real
wall to block the light.

From what I understand, the faked wall will actually emit a strong light
(because of ambient 20) but it isn't visible to the camera, only radiosity
reacts to it.. And perhaps objects with reflection reacts to it also, in
which case these objects will need uncommon finish statements.

Sounds strange that this should allow for lower settings for radiosity.

I'll experiment when I get the time.
You are welcome to post an example.

Regards,
Hugo
