[Max] General Discussion / handle heavy scenes causing high ram usage (automotive)
« on: 2017-03-10, 12:50:29 »
Hi,
i just want to know your experiences on how to handle heavy scenes with large amount of polygons at high resolutions and low RAM such as a 32GB workstation for example.
Since time pasts and the quality of the models gets higher and higher i'm running more and more often to max crashes if i want to render high resolution renders >4k with >30mil polygons (CAD files). I know that the internal resolution is set to 1 by default which is great but i need further optimizations just to get a more stable scene on rendering for production as i get crashes even at 2-3k without any displacement or render elements. I'm working on a 32GB workstation at home. Same scenes working fine at workstations with 96GB at work but i need to get workarounds for my 32GB workstation.
I read at corona helpdesk something about "Reduce the total number of instances". Normally i prepare all my scenes by deleting all mirrorable parts and then mirror them as instance again. So now i'm a bit confused a little bit with that "Reduce the total number of instances". Which way is now better to reduce ram usage?
What exactly corona does when "lowmem" is activated? How much it can help for render above 4k?
What or how high are the benefits of disabling the VFB? Any drawbacks? Anyone with experience here?
No option:
satisfy with low res
reduce polygon size
Also i could imagine a "high res production" mode at corona which can be activated optionally where the VFB shows only a 10-20% image resolution just to see progress and have control on post process while corona renders internally a resolution like 12k. This could be really helpful as i know that from Autodesk VRED which already have this kind of feature.
Thanks for any tips or help!
Cheers,
Duron
