pradipta Posted September 14, 2006 Share Posted September 14, 2006 I had this unique problem when vray does not render certain buckets in a scene. It shows an Illumination error and completely blacks out the bucket or sometime an entire row/column and proceeds to the next bucket. Can anyone tell me what may be the reason behind it. Thanks in advance Link to comment Share on other sites More sharing options...
atp-design Posted September 15, 2006 Share Posted September 15, 2006 can you send the scene ? Link to comment Share on other sites More sharing options...
pradipta Posted September 15, 2006 Author Share Posted September 15, 2006 The scene is too big, I will see if I can extract and send some part of that. Thanks a lot for your concern. Link to comment Share on other sites More sharing options...
FlytE Posted September 15, 2006 Share Posted September 15, 2006 If its the same problem I have encountered ( sounds like it) then its because you are running out of memory. Try either rendering parts of your scene at a time, or rendering to a vray raw image format. Link to comment Share on other sites More sharing options...
Christopher Nichols Posted September 15, 2006 Share Posted September 15, 2006 Use smaller buckets Link to comment Share on other sites More sharing options...
pradipta Posted September 15, 2006 Author Share Posted September 15, 2006 Actually i calculated LC and IR maps for half resolution of the actual animation resolution. When i am rendering the final sequence using both the light data it is giving that black bucket with error msg. When i am rendering in the resoluton i used for calculating light data it is coming up fine. But, i used this technique for some other projects on the same machine before and that was perfect. Is there something wrong from the scene itself? Link to comment Share on other sites More sharing options...
jvlive Posted September 17, 2006 Share Posted September 17, 2006 did you try restarting max? Link to comment Share on other sites More sharing options...
pradipta Posted September 17, 2006 Author Share Posted September 17, 2006 Julius, no. i didnt restart 3dsmax after that. i will rework on the file again. Hope that was a memory problem. Link to comment Share on other sites More sharing options...
pradipta Posted September 19, 2006 Author Share Posted September 19, 2006 I treied evrything from restaring my comp to reducing the bucket size but nothing seems working. i am getting this error: Unhandled Exception: rendering region (64,0)-(96,32) Last marker is at ....renderlight.cpp, line 300: VRenderLight::eval(), calling LightDesc::Illuminate() can anyone help me in this, Thanks a lot.

FlytE Posted September 19, 2006 Share Posted September 19, 2006 try doing creating a 3GB switch and re-rendering. That worked for me in the past: http://www.chaosgroup.com/forum/phpBB2/viewtopic.php?t=14564 Also, try rendering regions and pasting them all together, instead of rendering one whole image.

These to me sound like errors you need to report ot chaosgroup... not on the cgrachitect forum. I would try on that forum. Link to comment Share on other sites More sharing options...
pradipta Posted September 20, 2006 Author Share Posted September 20, 2006 Andy, i will try that now. The animation is around 2400 frames and my comp config is dual Xeon with 2 gb ddr ram and 256mb NVidia card. Thanks for the link, i hope that will work.

Sergio Posted October 10, 2006 Share Posted October 10, 2006 Hi pradipta, looks like I am having the same problem myself; did you manage to find what the problem was? Regards Srdjan Link to comment Share on other sites More sharing options...
pradipta Posted October 11, 2006 Author Share Posted October 11, 2006 Hi pradipta, looks like I am having the same problem myself; did you manage to find what the problem was? Regards Srdjan Sergio, Actually i calculated LC and IR maps for half resolution of the actual animation resolution. When i am rendering the final sequence using both the light data it is giving that black bucket with error msg. This is what I was doing before. I managed to solve the problem by using same resolution for calculating LC and IR map data and the final render. Link to comment Share on other sites More sharing options...
Sergio Posted October 11, 2006 Share Posted October 11, 2006 Hi pradipta, thanks for replying to my message I see, it makes the sence, in your case. I did not do precalculation, I was only rendering the still, and that would happend to me. RAM usage is just below 600Mb, out of 2Gb on my computer. Looks like I dont have that problem on much smaller resolution, originally rendering 2000x1500. Another problem might be in Simian materials for the glass, or reflective/refractive in general. I also used HDRI, and one of those must be clashing somehow. Last night I rendered at 1500 wide, and it worked with warning only, no errors. Vray is wierd sometimes , or I am doing something wrong Regards Srdjan Link to comment Share on other sites More sharing options...
