Deetee Posted July 5, 2011 Share Posted July 5, 2011 (edited) hey guys... Im using 3Ds Max design 2011. Vray 64bit window 7 8GB Ram Im trying to render a very high polygon scene. with a lot a lot of plantation. all those plantation, shrubs, i've already made it vrayproxy.. same goes to any others high polygon objects, i made it into proxy to save more memories while rendering... but the thing is it always fail to render. it seems to be due to insufficient memory, but im not sure if it is really due to memory issue. i had 8GB Ram and im using window 7 64 bits. but when the rendering is running, it always crashed when the memory is used at 3k+ when it crash, the whole 3Ds max design instantly crashed and close down without a warning or anything... but the thing is when i send for render through backburner, it seems to be running alright. it render smoothly and it even hits memory used: 5k+ can anyone guide me how can i solve this issue?

notamondayfan Posted July 5, 2011 Share Posted July 5, 2011 If it renders through backburner, then it sounds like a ram issue. Max and it's UI, plugins, etc all use RAM, so by using backburner you are saving RAM. I wouldn't see a problem if it renders through backburner, as I only use backburner anyway, but if you want it to render inside Max, then look at things like texture map sizes, geometry, and try to be as economic as possible with these. If you have trees in the background could you replace these for images, etc? Deano Link to comment Share on other sites More sharing options...
dande Posted July 5, 2011 Share Posted July 5, 2011 You can split your file up into separate files. Put your vegetation in a seperate max file. You can then xref them together. Render the 2 files separately and then put the renders together in post. Link to comment Share on other sites More sharing options...
Lehm Posted July 5, 2011 Share Posted July 5, 2011 What are your V-ray memory settings? (You find them in Settings->V-Ray::System->Raycaster params) Link to comment Share on other sites More sharing options...

Deano but the problem is when i render at my own machine locally, it crash at memory used 3k+.... using backburner, it able to hit memory used 5k.. cant be 1k memory used on max UI, plugin etc right? more over my machine has 8GB ram. but i notice that there are certain other camera sometimes render locally without go through backburner seems to able to render fine though. and it reach 4k+ memory used. You can split your file up into separate files. Put your vegetation in a seperate max file. You can then xref them together. Render the 2 files separately and then put the renders together in post. i already proxy all my vegetation... except got some certain trees that generate by onyx, as i wanna preserve the onyx parameter. i know proxy works differently from xref, but if proxy cant help in prevent crashing, does xref able to do better job for this? i used to thought proxy are better way to optimize the scene compare to xref. might try later... thanks for the suggestion, it has been 2 years ago since my last try on xref. What are your V-ray memory settings? (You find them in Settings->V-Ray::System->Raycaster params) what can i set within v-ray memory settings? the only thing i changed is dynamic memory limit: 12000MB (default is 400mb) default geometry: auto (i leave it at default setting) is there anything else i can mess with system?

Lehm Posted July 6, 2011 Share Posted July 6, 2011 You have it set to 12GB when you only have 8GB of memory? Try setting it to 6GB and see if it still crashes. Link to comment Share on other sites More sharing options...

THANKS!!! this helps me!!! i used to set 12GB back in my previous company as i have 12GB Ram back then... and i never thought by setting exceed the actual value of our RAM would cause any problem... thanks!!! currently i can render locally and memory used 6.5k thanks a lot Lehm!!!

Deetee Posted July 6, 2011 Author Share Posted July 6, 2011 btw.... mind if i ask what is the default geometry about??? by default, it is set to "auto". what it does when i set to "static" or "dynamic"? Link to comment Share on other sites More sharing options...
Lehm Posted July 6, 2011 Share Posted July 6, 2011 btw.... mind if i ask what is the default geometry about??? by default, it is set to "auto". what it does when i set to "static" or "dynamic"? Its generally best to leave that at auto. But what it does is tell V-Ray where to store geometry. If its set to static its going to load everything into memory and leave it there. This is much faster but takes alot more memory. Dynamic only loads what is needed for the currently rendering buckets, as soon as it doesn't need it it gets unloaded from memory. The next time it needs that piece of geometry it will have to go back to the disk to get it. This will cause the rendering to be slower, but allow larger scenes to be rendered. Auto lets V-Ray decided what should permanently be loaded and what should be kept on the disk. Link to comment Share on other sites More sharing options...
