This is my first post here and sadly it is because I am experiencing some unhandled exception errors with my scene file. The Vray Exception message told me to send my vraylog.txt and a portion of my scene to the above address at vray@chaossw.com however my emails have been returned as undeliverable dozens of times. I just want to make sure that I’m following the correct procedure and if not, how should I go about handling this properly?
I’ve had two seperate unhandled exceptions with this particular project.
UNHANDLED EXCEPTION: Irradiance map thread
Last marker is at P:\dev\LocalVSS\vray\vrender\src\renderlight.cpp, line 300: VrenderLight::eval(), calling LightDesc::Illuminate()
UNHANDLED EXCEPTION: Processing Lighting (Or something to this effect)
Last marker looked virtually identical
The second error occured while using DR on all of the render slaves, but not my workstation.
I’m using Vray 1.47.03 on MAX 8
Thank you in advance for your help. This is kind of a show stopper for a project expecting to be delivered so I’m fairly anxious to get this issue resolved. It could very well be user error as I am only 1 month into Vray usage.

well the email is simply wrong…you might wanna try info@chaosgroup.com

Wow Thanks. I guess the Unhandled Exception error message dialogue needs an update then - unless it’s been changed in releases later then 1.47.03 allready. Ok I’ll try the new address and thanks for the quick response.

@ MegaPixel
Can you please send me your scene or a piece of it, which still produces the
error at < nikki@chaosgroup.com >
BTW, is there a Daylight system in it ? If yes, don’t use it, that is not supported by V-Ray and an unhandled exception error is always returned.
Best regards,

Hi Candelero.
I’m trying to figure out the best way to host my very large scene file. Even compressed, it’s almost 20 megs. What I have done was stripped out all nonessential objects and textures and zipped up a cleaned version of the scene at the following link below:
Scene (About 3.5 Mb)

Thank you for offering to assist me. I hope the error can still be reproduced. Let me know what you find.

It’s been a while since I wrote on this problem and thought I’d give an update.
For those who don’t know, Candelero has been assisting me with troubleshooting this scene from day one. I eventually sent him my entire scene (All models, textures, etc…) and let him render it on his end. 15.5 hours later on one machine (Not using DR) he completed a rendering and sent it back to me. He could not reproduce my Unhandled Exception.
It should be noted that I too can also get this scene to render on my workstation alone. All of my problems however seem to be coming from my Distributed Rendering setup. I did another DR render this past weekend and developed another Unhandled Eception, howevr this time it seemed to be memory related. Here are the last few lines of my Vraylog.txt:
My Vraylog.txt:

I have 4 gigs of memory on my workstation, no the 3 /GB switch is not activated “yet” and my 3 DR slaves only have 2 Gigs. If you look at the log above, the crash seems to come right after the IR map is transfered to one of my render slaves. Does this mean that the memory problem is on the slaves rather then my workstation? Also, the task manager showed 2.44 GB of PF usage on my workstation when the crash happened.
New questions:
-Will enabling the 3 /GB switch on my workstation help anything?
-Should all of my DR Render Slaves have the same amount of RAM my workstation does?
-Does Vray have any memory management features to improve on things like this?
-Can I autosave my IR map during DR mode? (I lost a 30 hour IR calculation on this crash 
)
-Could rediculous render settings have caused the memory crash? (I’m still playing with render values I don’t know much about…)
Welp, there is my update. Hope I can get this process ironed out so my future is smooth sailing. Thanks in advance for any additional help you can offer me. Thanks again especially to Nikki for the immediate attention to this issue I was given.
