erickdt Posted May 18, 2009 Share Posted May 18, 2009 Hello All, I am attempting to render an animation over a few of my machines via. VRay distributed rendering. I keep recieving the following error (see attached) on my slave machines. Does anybody have any idea how to solve this issue? Thanks in advance!

Tommy L Posted May 19, 2009 Share Posted May 19, 2009 Vray Exception is usually caused by the machine running out of RAM. Do you have the same amount of RAM in the slave machines as in the workstation? Does it render ok on the workstation? Try cutting back on the render settings and render size, strip everything back and start from very basic settings (turn off glossies, 1 bounce reflection, no displacement etc) then try again. If it works, add the higher settings back gradually until you can push the slaves no further. Link to comment Share on other sites More sharing options...
erickdt Posted May 19, 2009 Author Share Posted May 19, 2009 Hmm. Ill try that when I get into the office. All machines haves 6G of RAM and 8 processors. It is a complex scene though (lots of geometry) but I do think it could be simplified. Link to comment Share on other sites More sharing options...
Tommy L Posted May 19, 2009 Share Posted May 19, 2009 Are you using displacement? That would be the first thing I would try switching off. Followed by glossies. Link to comment Share on other sites More sharing options...
erickdt Posted May 19, 2009 Author Share Posted May 19, 2009 I don't have displacement anywhere in the file. I tried turning off glossies but to no avail. Link to comment Share on other sites More sharing options...
erickdt Posted May 19, 2009 Author Share Posted May 19, 2009 I'm thinking that the scene size might be the problem. Attached you'll find the scene's summary info. 15984.6M of virtual memory can't be a good thing. Could this be the issue? Link to comment Share on other sites More sharing options...
Tommy L Posted May 19, 2009 Share Posted May 19, 2009 Ive never paid any attention to that figure, so i dont really know whats normal. You have 5million polys, which isnt huge, but its big enough to wave flags if you are not doing anything to optimize your scene. Link to comment Share on other sites More sharing options...
Tommy L Posted May 19, 2009 Share Posted May 19, 2009 I just read the error. You have how many spot lights? What kind of shadows are you using? Post your render settings also. Link to comment Share on other sites More sharing options...

erickdt Posted May 19, 2009 Author Share Posted May 19, 2009 I just read the error. You have how many spot lights? What kind of shadows are you using? Post your render settings also. There's about 40 spotlights in the scene along with 4 VRay lights. There all set to VRay shadows or no shadows at all. Link to comment Share on other sites More sharing options...
Tommy L Posted May 19, 2009 Share Posted May 19, 2009 Is it a night shot? You have to give some more information, the error itself is rather vague. Link to comment Share on other sites More sharing options...
erickdt Posted May 19, 2009 Author Share Posted May 19, 2009 I design tradeshow booths. The scene I'm working on is one of a 110'x100' tradeshow booth. There are spot lights over the various elements in the booth to "punch them out" as well as a few spots with projector maps to give the impression of projections. I'm pretty convinced that my issue is the scene geometry which is fairly heavy. I am currently in the process of converting everything to VRay proxies to see if that solves the issue. Still none of this makes sense to me as all of the machines that I am using have 8 processors and 6 gigs of RAM on Windows XP 64. Memory should not be an issue. No? I have managed to get it rendering by adjust the raycaster settings but that seems to really slow down light cache and irradiance map calculations.

Tommy L Posted May 19, 2009 Share Posted May 19, 2009 Well you have much more chance of solving the issue by posting settings... Link to comment Share on other sites More sharing options...

Tommy L Posted May 19, 2009 Share Posted May 19, 2009 I would try a couple of things. 1: Limnit the reflection (max depth) to 2. 2: Lower the AA to -1 / 0 for testing. For the final just go to 1/3 Link to comment Share on other sites More sharing options...
erickdt Posted May 21, 2009 Author Share Posted May 21, 2009 So here's the update: it turns out that the excessive geometry in the scene was the issue (5 million + faces). I remodeled that entire portion of the scene bringing the face count down to 60,000. The geometry that was removed wasn't seen in the scene so no loss there. Anyway, my animation is happily rendering on my 5 8 core machines. This whole process has been an enlightening and at times very frustrating experience for someone who hasn't done many animations. Thank you all for your help, especially Tommy L and the Chaos Group tech support team. Link to comment Share on other sites More sharing options...
