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,

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.

Well, if I can put up with the six fans in my computer...

What code needs adding to allow that?

I assume save_file the first time and load_file when the render is
continued. Anything else?

I really want to render a bigger version of a scene I've got with radiosity,
but I estimate rendering time of over 50 hours

An iMac has no fan at all and they don't overhead either...

Yeah, that should do the trick. The other radiosity settings (including
pretrace_start & pretrace_end) should stay the same for best results.

Yes, an iMac runs POV, ya schmucks.

It would run Moray if the the coders weren't too lazy or too incompetent
to write a Mac version.

Or if they had the time, tools, and knowledge to do so...programming 
isn't always easy, and learning to program for a new platform is a lot 
of work.
Anyway, we have plenty of free and shareware modellers. From what I saw 
of Moray(running it in emulation under SoftWindows), there wasn't much 
special about it except POV output and mostly POV-specific features. And 
besides, would a Mac version of Moray be any good? Mac ports of PC 
software often aren't, especially when ported by someone new to 
programming Macs and who doesn't actually use Macs.
Hmm, maybe my next Cocoa project should be a simple POV modeller for OS 
X...with a scripting language, of course. :-)

I know. I'm just mocking the poster for giving us the nth iteration of
"hmph, Macs! Do they even run any software?".

  Okay, be nice now :) Lutz is neither lazy nor incompetent but if he
chooses to devote his time to a Windows-based modeller then that is his
choice to make. Lutz is also a longtime POV-Team member.

My original g3/300 iBook has a fan that's so loud, people look to see
what that noise is, in class.

iBooks don't have a fan!  What you hear is either your CD or hard drive.  If
the hard drive is very noisy, you should send it in for repair.  If it is
the CD-ROM drive, remove the CD inside or place your iBook on something
non-vibrating.

I was talking about the current iMacs, not the two year old ones.

My point merely was that buying any computer which is quiet enough to leave
on all day and night, even if it is only half the speed of the noisy ones
will ultimately be more effective:  If you can leave the noisy one on 8
hours a day compared to 24 hours of the half the speed one, well, the half
the speed one will still be 50% faster when rendering complex scenes.

No reason for a major discussion ;-)   Just buy a slow one ($300) for your
room and connect the two via Ethernet :-)

I'm sorry but thats completely out of order, I don't wish to get into an
argument but lets say you are a Windows user, lets be realistic, because
after-all I'm not a fan of Bill Gates (far from it) but he does have a
monopoly and Windows is the largest consumer OS, if I remember correctly.
Therefore if you use Windows and a majority of people you know use Windows,
and you know how to program in Windows, and there are less Mac users,
therefore less Mac users screaming for a good modeller, which would you
choose?  I wouldn't call it lazyness or incompetence, more like common
sense.

My solution was to build a house and put the computers at one end and my
bed at the other.  Worked like a charm.
