I have a question which probably has been already answered. If so, sorry.
The question is: when something it's being illuminated only with radiosity,
normal effect disappear. That is my experience. Is there a way to solve
this without adding real lights?. Thanks.

  Apparently you have not experimented by adding "normal on" inside the
radiosity block.

Yes I didn't, thanks for the information. I'll try and then I'll tell you.

Be warned that adding normal on will make the render takes more time, possibly a 
lot more.

If you haven't gone through the "radiosity tutorial" in the manual, it's a 
great reference for what the radiosity settings do (section 2.3.7).  It 
makes more sense to me than simply reading the actual manual section on 
Radiosity.  I'm constant referring to it, though I still generally end up 
only tweaking "count" and "error_bound".

Well, I actually read it long ago but it seemed to be a bit useless, let me
explain. As far as I read, in summary the conclusion of that tutorial was
"there are two or three obvios parameters, for the rest of them, explore
yourself the results when changing them".

But in this particular case I recognize my error. When I found the problem I
should have taken a look again to the tutorial.
