I've been rendering at 2048*1536 and found that if I stop and resume it
later (ie all day, then turn it off at night, then continue the next day) a
visible line occurs from where the render starts again.  My 4 day render for
example has three visible lines, where it appers to get lighter; is there
anyway to stop this apart from leaving it rendering constantly?  This could
be a fault of Moray, but to be honest I'm suspecting its just something I'm
doing wrong with POV.  Thanks

Are you using radiosity? If so, stopping the render and starting again 
will often cause visible breaks. I don't think there is a way to work 
around this.

Except using MegaPOV radiosity - but that would reguire some actual *shudder*
hand-editing of your POV file...
I can state for a fact that with MegaPOV it is possible to continue a radiosity
render without problems.

I forgot to mention I was using Radiosity, but with MegaPOV.  Hand-editing
of my POV file, you must be joking, I'll have to find a way to work around
it (by the time I've finished my Moray file I barely know where I am within
Moray let alone POV, unless its hand-coded from scratch I rarely know whats
going on).

MegaPOV radiosity requires some different options than POV 3.1...using 
the same settings won't work. There are some new parameters, so you will 
probably have to edit the file by hand.
However, you don't have to code anything, there are plenty of examples 
of good radiosity settings on these newsgroups, and MegaPOV radiosity 
settings are much less scene-dependant than the old radiosity. Some were 
recently posted in povray.binaries.images and there are probably some 
good bits in the *.scene-files groups.

IIRC you should find the radiosity parameters in the main .pov file, i.e. the
file with the same name as your Moray scene file. The parameters need to be
somewhat different from regular POV, and two useful new options are save_file
and load_file, which will save and load your radiosity data to a file (see MP
docs for more info).
You would probably have to start (and re-start) the render directly from POV,
because otherwise I think Moray will overwrite your changes.

Why do you stop your render at night?  I have found that I get upwards of
7-8 hours of good rendertime by leaving my machine cranking while I sleep.
Not only that, but if you get up and go to work, you will typically find
that you have upwards of 15-17 hours or more worth of machine time that you
aren't on it messing with it.

Er yeah but my computer is in my bedroom, and its an AMD TBird, yes it has
one hell of a fan and too top it off, my GFx card likes to overheat every so
often so I leave the lid of making it even more delightful.

A bit of insomnia doesn't help either :)

That's pretty close to the reason that I don't leave my machine on 
overnight.  Without the overheating graphics card bit or the insomnia 
bit.

I find it annoying to sleep with my head about five feet from a couple of 
computer fans.

Bye for now,
     Jamie.

Same here, except in my case it's four feet.  Additionally, if the hard disk
spins down, it sounds like a jet airplane taking off when it starts up
again.
