nakulchauhan Posted March 28, 2009 Share Posted March 28, 2009 Hi People!!! I'm facing a serious situation and I'm sure is faced by many people. I need to solution to that. Problem is like this. I'm rendering a large scene. Large is terms of objects I would say. There are about 3500-4000 objects in the scene. I'm using 3dsmax for this with vray renderer. For GI I'm using irradiance for primary and light cache for secondary bounces. My problem is, the light cache takes a hell lot of time to calculate. The scene resolution is not much, it's 720 by 576. Even settings of light cache are pretty low only. I'm attaching the settings of light cache along Please suggest a solution. Thanks Nakul Chauhan Link to comment Share on other sites More sharing options...
Hoa Dinh Posted March 28, 2009 Share Posted March 28, 2009 I had this problem one time. The reason is one bad opject, you can try hide almost opjects in your scene, render, unhide some one and rerender.... Hope you can solve it. Link to comment Share on other sites More sharing options...
kippu Posted March 28, 2009 Share Posted March 28, 2009 check for "architectural " materials or fur objects or lots of proxy objects , Link to comment Share on other sites More sharing options...
nakulchauhan Posted March 29, 2009 Author Share Posted March 29, 2009 Thanks a lot for replies. I guess in my case it's the proxy problem. I have lots and lots of proxies in my file. But i can't help using them otherwise. It's a landscape environment. And that's why contain a lot of trees. Is there any fix to that. Link to comment Share on other sites More sharing options...
kippu Posted March 29, 2009 Share Posted March 29, 2009 increase your dynamic memory ,how much ram have you got? Link to comment Share on other sites More sharing options...
nakulchauhan Posted March 29, 2009 Author Share Posted March 29, 2009 The system's configuration is pretty fine only. using 2 GHz, dual quad xeons with 4 GB or RAM. I've already pumped up dynamic memory limit to 2500MB. Link to comment Share on other sites More sharing options...

Cocytus09 Posted March 30, 2009 Share Posted March 30, 2009 Check the "vray messages" dialog box for the "max tree depth: #" when you hit the render button, and match it on the "vray system" parameter. For example if in the vray messages dialog box it says: "Max tree depth: 35", change the value to 35 or 36 on the vray system parameters. That solved a lot of my crashing problems because the original setting is 60 or 80 (depending on vray version) and it's just overkill on your RAM usage. Lower your dynamic memory limit back to 400, and try it. If it still crashes, up the dynamic memory by 50MB until you see some improvement on the render time. Hope it helps.

nakulchauhan Posted March 30, 2009 Author Share Posted March 30, 2009 Thanks a lot. I'll try it. Will contact if i still face a problem. Thanks again:). Link to comment Share on other sites More sharing options...
Ruprect Posted March 31, 2009 Share Posted March 31, 2009 I just encounter this problem myself. It seems to be caused by a rogue raytrace material in the scene. I solved it by using the vray scene convertor. Link to comment Share on other sites More sharing options...
selos69 Posted April 5, 2009 Share Posted April 5, 2009 Have you got any displacement in the scene? Link to comment Share on other sites More sharing options...
