Constant shut down errors during rendering
show user profile  eightangrybears
I am at my wits end with this one. I just purchased a brand new workstation with tons of power. 48 GB RAM, dual quad core, solid state drives, etc. and yet every time I try and render anything big, 3ds max dies and sends me an error report. I have an animation I am trying to render that is VERY LARGE, in terms of file size (right now it is 808 MB) and every computer I try and render it on, it crashes 3ds max. So I tried a different, smaller, indoor scene (single shot render) and the same thing happened. It's not crashing my machine, but 3ds max only.

The renderings take a while to pre-process and then translate, but then they get about 500-600 frames deep and the program crashes.

Unfortunately, I have A LOT of very detailed items that I move past (get very close) and so reducing polygons or vertices is not really an option at this point. And just about everything moves at some point to its final resting place so whatever tricks associated with non-moving objects are pretty much moot. Aside from rendering a hundred frames at a time (which means 30 pre-processes and 30 initial translations), I have no idea what to do.

I have heard of certain optimizer modifiers, but unfortunately, I have also heard that they dramatically reduce the quality of the object. I am also running this at a medium quality, low on all the other settings, AVI with 85% MPEG compression and only a window size of 720x450.

I am sort of blown away that this can even happen on this machine. It shouldn't. We all pay a lot of money to use and have these products at our disposal and the program can't handle an 800 mb file? I have heard of people with file sizes over 2TB and they don't have issues.

Any help I can get would be awesome. Thanks

To add a little info, the current model says it has 11,000,000 polygons and 9,000,000 vertices. I know this is a lot and I wish I could reduce the complexity of most of these objects, but the camera passes right by them and the client has stressed importance on seeing the full model, not a lego version of it...

First of all, don't render to AVI. Render to uncompressed image files, compile it later on. This way you never lose rendered frames.

Obvious suggestion but have you tried reinstalling max and everything related (plugins, renderers...)?

Does it crash on random or on specific frames?

What error does max crash with?

you can try the pro optimizer modifier to lower level of detail by percentage. this works pretty well. also. set up LOD for render and that can automate the level of detail depending on camera distance from objects(found in Utilitie's panel > more... > level of detail.)

you shouldnt need 10 million poly's for for much. I work with high end / high resolution 3d scan data everyday that has color per vertex and real time shading that doesn't even get close to that.

-horizon is exactly right you should be combining images sequences in post.
-Look at your shaders- reflection/refraction shaders too those can be a killer. It would be great to see the scene if at all possible. I could give it a go here.

P.S. Max is only a very small percentage of the resources you posted.

are the objects imported from another format ?.. (like .obj .iges or whatever)

I have had problems back in the day where a single object out of many would cause a render to fail.
Unfortunately this meant I had to hide objects one at a time, until I figured out who the culprit was..

Terribly boring signature.

Well, I found out last night after some more due dilligence that rendering to AVI is frowned upon (basically because it causes crashes it sounds like). This makes me wonder, though. Why would Autodesk recommend that you render to avi (in their tutorials) if so many people have issues with this?

Also, I heard using the pro optimizer modifier can drastically reduce the quality of the objects. It sounds from these last few replies though that it can work variably depending on the distance from the camera. Do I need to select all of my objects one by one and add this modifier, though? There are A LOT of objects, is all...Or, am I getting this wrong and you are saying to set up LOD in the render dialog to automate the detail level depending on distance? If so, how do you go about doing that?

Lastly, I did import the majority of the data from inventor. I did a conversion early on and separated the files up to make it easier to work on and recombined them later. I would be very upset with Autodesk if their file conversion process is the culprit here. How can they possibly make products that cause such massive errors when they recommend them together?

So, I reworked my model all night last night, thinking I had found the culprit in the unusually heavy equipment install model. I took that section alone down from 470 MB to 120 MB with some reworks, but still expoting from Inventor to 3ds.

My overall model went from 830 MB to 365 MB, or a total savings of 465 MB. I was thinking I was onto something. I set it up to render again and left at 4:30 AM last night to go get an hour of sleep. I started my laptop with the file, too because I am using that to render as well. When I awoke (after 2 hours of sleeping), the laptop was still going...pretty strong. No error report at least. I made my way back to the office and the program had shut down after only 16 frames. I seriously don't get it...

So, I proceeded to reinstall 3ds max, the nvidia quadro 4000 driver (from autodesk) and the service pack for 3ds. I am hoping that one of these three things will help this problem because now it doesn't seems as much like the program as it does the computer (which is even more concerning since it is brand new and has more than the power necessary to complete these tasks).

Any help here would be appreciated. Thanks,

Are you running 64 bit versions of everything?

What are your material paths like? I had an issue a while back that seemed to stem from the fact I was using massive material files. I hav 24gb of ram on my machine and I like you kept on getting this render erroring issue. Max would ranomly shut down without an error message, or anything, but the PC would be fine. So I resaved everything as a JPEG and it stopped crashing out. Do you have any issues opening your material editor? often my scene would crash just from opening that. Also what version of max are you using?
