error: UNHANDLED EXCEPTION: Irradiance map thread Last marker is at .\src\material.cp

Hi everyone

It seems that I just can't render a scene. When I try to do so, after a while, Vray crashes (and so do Max, of course).

It is extremely frustrating as this scene had been a LOT of work.

I got 3Ds Max 2009, Vray 1.50 SP2, (both 64bits) with 4GB RAM.

I thought it could come from a missing mesh in a proxy, but I removed it and I still got the problem. I got no error or warning before crash. The crash happens during the Light Cache computing or sometimes during the IR prepass, it even happens sometimes on rendering.

Needless to say that it is VERY frustrating, this scene is over for months now and I still haven't been able to view any final renders.

The Vray log is always the same:

"error: UNHANDLED EXCEPTION: Irradiance map thread
Last marker is at .\src\material.cpp, line 1746: VRayMtl::shade() {2}"

I don't like to complaint, but please, please, 100xplease, help me!

Well, this thing is driving me crazy but I think it's simply a RAM problem.

I have a small render farm of 4 PC and I try to render one view on each PC. Each PC is, as I said, Max2009+Vray 1.50SP2 (both 64bits), CPU 9550 Core2 Quad, 4GB RAM.

The error message is not the same depending on the view. On anohter PC I just got this one:

error: UNHANDLED EXCEPTION: Irradiance map thread
Last marker is at .\src\displacementfunc.cpp, line 196: Done evaluating displacement function

But it can't be a displacement map problem in itself, as I tried to render without displacement on a PC and it is still crashing.

Also, the crash happens more or less quickly depending on quality setting and resolution. With high settings/high res, the crash happens during LC calculation, with lower settings/res it takes place on rendering.

Plus, two month ago I tried to render a view from my main PC, which got the same softwares but which is CPU i7+8GB and it rendered fine (until I had a black out in my flat, which of course put an end to the render )

The problem is I can't render it from my main PC as I am working with it, if I launch a render from it all my RAM is sucked and I can't work on antoher CGI project.

I'm gonna try to launch a render on my main PC tonight and see tomorrow if it crashed during the night, if not I guess I'll just have to buy more RAM for one of my render farm PC (and another motherboard, as 4GB is the maximum this one can stand)

If it crashed too I guess the file got corrupted in some way and I guess I'll just have to spend ages trying to find who's guilty in this hell of polys.

Needless to say that both of this options are pretty annoying.

I'm a bit depressed

Anyway I still would like to have your opinion about it

I.E I don't understand why it is crashing as I thought that by setting the Dynamic Memory limit it would be possible to render huge scene even with very low RAM system. Am I wrong?

Thanks

What is the setting for the page file on your system? Also, can you get me that scene to vlado@chaosgroup.com so that I can make a few tests here?

Best regards,
Vlado

shouldnt you update to sp3? sp2 had bugs in it. just log in to your user account on this site where you downloaded your version of vray
