3ds max 2011, PC shuts off and restart while rendering complex scene

Hi, I'm trying to render out the final scene of a very long project you might have seen in pimping and previews or around the net:

[ame]http://www.youtube.com/watch?v=X-Qlz2631Ic[/ame]


My system is rebooting without any warnings while rendering the scene, sometimes it will manage 2 or 3 finished frames before shutting down. I'm using scanline render in max 2011, I have 4GB of ram in a 64 bit system with 64bit version of max. My processor is an i5 clocked at 4ghz on each core.

Im not doing anything too fancy with the rendering, its 1 skylight, 1 spotlight with almost completely default lighttracer options, and the frames themselves only take like 40 seconds to render out. I guess it's running out of memory or something?

Tbh, I dont even know what specific information to provide which would be relevant, I would LOVE any help, as I NEED this video completed as fast as humanly possible.

Thanks in advance,

Jay

P.S. It's not a heat issue, Ive monitored temperature and it never goes above 55 degrees.

    that could be a sign of faulty memory. certainly have seen this myself and max seems to be one of the few programs that really exploit any flaws on the memorysticks. unfortunately the only way to be safe is to use ECC memory sticks.

    if max/windows was merely running out of memory it would tell you and/or simply crash.

    hmm that would be bad as this is a very new PC.

    Ive managed to have some luck by reducing the number of, samples or something (cant remember exactly and its rendering now so i cant check). seems the lower I make that (was at 150 now at 50) the more frames I can get done before crashing and while it made the backdrop sky kind of blotchy i just turned off advanced lighting on that and made it self illuminated and that seems fine now.

    hopefully I can get through rendering this then investiate why it crashes at all.

    Is your i5 overclocked? If so, try running some benchmark software to test the stability.

    Also, render to image files instead of directly to avi/mov, then compile them later.

    It sounds like something is overheating. It may be too much for your computer to handle. There is a safety feature in there to shut the pc off when it reaches a certain temperature. Used to happen to me on my old computer when too much was running for too long.

    by the way, that animation is incredible.

    Render to frames then composite? It might die but each time you'll get more and more of the job done. You can load the frames into ram player and save out a avi. Or use AfterEffects or if you're on max2011 it comes with composite formerly known as Toxik.

    It could be a plug-in or some other script that you have launch with max when it starts up?

    Render through backburner instead of max, it only launches the functions necessary to render. Launch Manger, Server and monitor, set the job to netrender and shut off max when it finishes sending the job. If you have other machines you can use install max, launch server and they'll pick up a few frames here and there too.

    A skylight can be expensive. it puts a light dome over your entire scene so if you have a giant ground plane it will create a giant light dome. Keep the scene small will keep the dome small and help with render times.

    Are the lights set to shadow map and what size is the map that you're using, you could get away with a smaller map but perhaps blur it a bit.

    Hey, yeah I've started rendering to frames instead of one big avi. I don't believe it's a heat issue b/c Ive run temperature monitors to check.

    Im doing OK at the moment, 228 frames in and no crash so far, so hopefully that one tweak I made is doing the trick. If I get more problems I will try the backburner thing. Thanks :) Very much looking forward to this project being finished hopefully tomorrow.

    You are most likely getting a blue screen. Windows hides them and reboots instead by default, google on how to disable system reboot on error, and you'll be able to see the error message next time.

    This sounds a lot like bad memory. The memory intensive rendering being the only thing that really uses it to it's absolute max and then it hits the bad sector and dies. (I had a similar problem a few years back - rendering was causing crashes after a few hours because of bad memory, temps were fine).

    Try getting a memory diagnostic tool and running that - see what comes up.

    As gannonroader said something is overheating, but I have a feeling it's power that is missing. If the PC overheats it usually shuts down completely. You mentioned that it reboots but also mentioned that it shuts down. Does it do both? or a reboot?

    If it reboots, then it sounds to me that you don't have enough power from your Power Supply! But if it shuts down, then looks like overheating (or memory as it was mentioned above) but then you will need to see what the error is. You can disable the auto restart on errors in windows by doing the following:

    Right click on "Computer" icon on the desktop and go to properties --> Go to "Advanced System Settings" (or Advanced if you are on WinXP) --> Click on the "Settings" button under the Startup and Recovery section (last one in the window) --> Uncheck "Automatically Restart" option under the System Failure section.

    This way if you are getting a blue screen, you will see it and usually it will indicate to you the error type/file and then a Google search can give you more info as to what the issue might be.

    Good luck

    run memtest 86+ overnight and see if it finds any errors.

    i'd say go with Vic's suggestions...

    try rendering with backburner, but turn off the viewcube beforehand (we had some issue with our renderfarm with that)

    as u stated that you monitored the heat i guess its not that, also false memory on a new pc seems odd, too!

    which renderer are u using?
    if its vray go into the render setup, into the Settings tab and under Vray: System put up the Dynamic memory limit to 4000 MB?
    You could also try and render one char first and then another pass with the other character...
    Turning off motion blur might help, too, you can then save the frames as .rpf and put motion blur on it via fusion or whatever
