Yes, I feel also the same. It's a side-effect of the trick used, but I
will try to minimize it. Blur doesn't has nothing to do with it, and
perhaps helps hidding the fact.

That's the problem, and my motivation to do the trick: I can't get that
kind of lighting only with pure rad and one light_source outside. Surely
it's possible, but I've not the patience needed to find and test the high
quality settings... I'm very lazy, do you remember? :)
The original image on the first post uses an extra area_light placed
carefully on the window hole, to simulate the external rad coming in, with
"Radiosity_Normal". The image called "faked_rad_normal.jpg" shows the same
setup with only the outside light (almost no visible rad effect). The image
"faked_rad_no-aa.jpg" uses also the same tricky extra light, but without
the area_light statement (to show better how it is placed).
I've tried this trick on my "alchlab" image done with Megapov, but seems
that it works better with 3.5. I will try to add an spotlight statement
automated to follow the sun position, to give it a more directional look.
