Hello and welcome.

 I posted an animation about a month ago in p.b.a that used radiosity.
There was some discussion on it then as well.
The animation I did was with a moving camera and stationary objects.  With
moving objects, you need to calculate rad each time consuming a lot of
render time and the results will not bend smoothly from frame to frame
because of the nature in the way rad data is calculated.  The same is
essentially true for stationary objects if you recalculate rad each time.
The way I made the animation though was by first rendering a high quality
version of the scene with rad and use 'save_file'.  You need to make sure
that you can see as much of all the objects in the scene as possible.  The
camera view here does not need to be the same as that used for the animation
as the rad data isn't essentially related to the camera position, but rather
the objects and the scene themselves.  For my animation I placed the camera
in between the 4 spheres looking down and used the fisheye camera type and
placed no-shadow mirrors around the outside.  This maximixes the visibility
of all the objects in the scene.  Once this is run at high quality, remove
the mirrors, place the camera wherever you want and use the 'load_file'
option for rad.  The scene will use this data instead of recalculating every
time and since you are using the same data for each scene, the animation
should blend relatively smoothly.
