Seems a sily question, but while rendering a scene with radiosity the  
computer decided to do a auto restart, this left the rca file available.  
So it's done 500 odd lines can I get it to read in the rca and finish the  
last 260ish lines if I use:

radiosity{
load_file "file-in.rca"
save_file "file-out.rca"
...settings for radiosity before things went pear-shaped...
}

will it take into account the radiosity of objects it's not rendering from  
the rca file?

As I started this before XMas you can understand why I'd like to be able  
to start from where it left off and know if this is going to work before I  
start it up again :)

Simply continue rendering with +C (no need to modify your scene in any
way). POV-Ray will automatically continue from where it left and take
the radiosity data in the rca file into account.

  That's exactly the purpose of the rca file (ie. so that +c will work
also with radiosity).

Yippee so it will take into account information already processed. OOC if  
I did do a load_file with a +srX and then join the two images together  
would that be equivalent to +c* if I had to switch it to another computer  
for some reason?

*manually joining the images afterwards of course.

  I have no idea. There might be something different if you do it that
way that might cause a visible line, but I have absolutely no experience
on this.

Of course, you could just bring the partially rendered output image and the
temporary radiosity data along with the source code to the other computer,
and then you could use +C and avoid worrying about doing a partial render.

Well now I know, as I attempted to restart this without asking (that'll  
teach me) +c is not an option and +srX does produce a line, shoot! Ah well  
take two.

Just finished the final render and blow me down if there isn't a line  
exactly where one showed up using +srX, so either a) reading in a  
partially completed rca file will do this or b) My scene got messed up; no  
bets being taken for option b :) I'll try a full (smaller) render without  
any rca data being read and see what happens. I know now you're supposed  
to use +c, but I'm curious as too what will happen.

I noticed that the line in your image is not perfectly horizontal. Are you
sure it's not a shadow as Steve suggested, or some other coincidence?

I think the non-horizontalness is an illusion caused by the placement of  
the spheres, but I've just posted to Steve and I'll start stripping it  
down later. Still got 140 lines to go of my small test and either it's  
still mosaicing or the focus is wrong, stopped and stripped that out I'll  
see what happens. I'll post the 320x240 as a teaser when it's ready :)
