render error: UNHANDLED EXCEPTION: Image prepass

[moifa]

hey guys,

 

I recently bought a second-hand Dell workstation and installed 3ds Max 2015 and Vray 3.2 on Window 7. I was testing the machine with a simple sphere, a floor and a vray plane light. If I render locally, it is fine. But when I render with DR, it gives me this "error: UNHANDLED EXCEPTION: Image prepass

Last marker is at ./src/globillummap.cpp, line 1932: GlobalIllumMap::buildLightMap() {5}".

 

 

There is nothing wrong with the scene, I test DR the same scene with an older Dell workstation. So there must be something wrong with the configuration on my new workstation. It shouldn't be a RAM issues, my new machine has 128GB RAM.

 

The scene renders fine locally, this error only comes up when I use irradiance map with DR. If I use Brute force with DR, it render fine also. Anybody have any idea what may cause this?

 

Thanks heaps!

It's doubtful it's a hardware problem, most likely it's a bad install or your having some network permission problems.

Check the version of V Ray installed in all your computers, also Max version.

Other than that you may want to contact Chaos group they may have more info for that code.

The Max and Vray versions on both machines are the same. I tried reinstall Vray, the problem still occurred. Then I reinstall Max and Vray altogether and it solves the problem.

 

Thanks guys.

I had this issue on an animation that I was sending out to a farm to render, never got to the bottom of what was causing it so we had to go with brute force - which actually worked out just fine in the end.
