Chenarch Posted January 11, 2012 Report Share Posted January 11, 2012 Hi everyone, I've added some elements to my very large scene and trying to get a comprehensive image. I added some lights and two sculptures. Scene is 2.5 million polygons. I have four principle lights shooting photos and a sun (parallel). The skylight object shoots 3,800,000 photons, window object shoots 3,600,000 and two radial lights at .1 intensity for general illum shoot 1,000,000 each. I've been sending to a Mac Pro Nehalem with (10) Renderama cameras employed. Total RAM on that machine is 12GB. For the first time, now Renderama errors occur due to "ran out of memory." Am I simply asking the MacPro with 12GB to do too much? Is there a way to render composite layers one by one? Are there ways to slenderize the files? Can I do things like delete unused .fac files, elements that are turned off, etc. It seems all this info will be sent to Renderama files. It also looks like Memory is not too expensive these days. Two 4GB sticks at OWC is only $66. Thanks all! Richard Quote Link to comment Share on other sites More sharing options...
Arketype Posted January 11, 2012 Report Share Posted January 11, 2012 Hi Richard, Are you rendering in "strips"? This can help with the RAM requirements (fewer GI points per strip) Dave Quote Link to comment Share on other sites More sharing options...
Chenarch Posted January 11, 2012 Author Report Share Posted January 11, 2012 Hi Dave, Thx for responding. Yes it's rendering in strips for a still image, one strip per camera. I reduced number of photons by 33% (total of 9.4 million down to 6.6 million) and then reduced cameras from 10 down to 6, and it seems to be back on track. I mean I was able to shoot the photons around the room and get a prelim image. Then ordered 16GB more RAM for that machine. It's very affordable these days. When I supercede a .fac with an updated .fac I sometimes just leave the old one there because it's just referenced anyway. Maybe clearing out the render files every now and then... ? Thanks again, Dave! Rich Hi Richard, Are you rendering in "strips"?

Tomas Egger Posted January 11, 2012 Report Share Posted January 11, 2012 Ola Rich, I hope to change your workflow soon :) Thanks Tom Quote Link to comment Share on other sites More sharing options...
Reuben.F Posted January 21, 2012 Report Share Posted January 21, 2012 Buy memory while its cheap because prices are volatile, ;) Quote Link to comment Share on other sites More sharing options...
