Hello,

   I'm now using radiosity for the first time and I've got a quick question.
I started a render yesterday that will probably take several days.  I had to
interrupt it today and when I resumed it with the +c option all the blocky
pixels at the bottom of the render window are gone.  It looks like its going
ok but I'm a little worried that maybe some information was lost from the
first few passes that it now doesn't have and if I need to restart from
scratch I'd rather know now then a few days from now.  Is it ok to use the
+c resume option with radiosity?  The documentation states it "displays the
partial image rendered so far" but I'm missing the blocky bottom 3/4th of my
previous render window.  Do I need to be worried?

Thanks,
Carl

When you interrupt a radiosity render the radiosity data file will not 
be removed (extension .rca).  When you resume, this data file will be 
used again.  So usually no need to worry but note that not all data 
stored in memory during a radiosity render is also written to the file 
so there might still be a visible break in the image.
