(Yes I realy do like playing with radiosity :)

After saving radiosity data, and then loading it with identical scene, the 
output image is little different. The image that loads data renders about 
x6 faster (count=300 error=1) and looks a little bit nicer that image that 
where outputet when saving radiosity.

I would like to have same quality with create+sava radiosity version and 
with load radiosity version - but to save more time (I want to do 
animation).

And Yes, I do use always_sample 0 :
in save version :
      save_file "rad2"
    //  load_file "rad2"
    //  always_sample 0
and next I'm re-rendering it with :
    //  save_file "rad2"
      load_file "rad2"
      always_sample 0


Another question - what excly data are stored in radiosity file ? 
It is save to move camera around, but I quess it will be NOT safe if camera 
will i.e. move to another room - or if it will view surfaces not visible 
while saving radiosity ?

And - can I change light's _colors_ (not position), like
light_source { <0,0,0> color rgb <clock,0,1-clock> }
or 
sphere { 0 100 pigment { color rgb x*clock } finish { ambient 1 } }

You should have a look at the documentation of 'always_sample'.  using
'always_sample off' disables gathering new samples during final trace. 
It's fairly obvious the result looks different.

I read it, so I quess I missinterpretate this part.
I want for clock==0 - gather samples, gather in final phase, and save all 
samples
else :
  laod data, do not gather enything, just use loaded data

or loaded data isn't enought to skip entire gathering - it is only some 
kind of optimization for speed-up gathering ?

  From my experience, in the "load version" you must specify the same 
error_bound and recursion_limit used on the "save version", because these 
values are apparently overridden and set again to defaults (and used for 
the calculations too).
