Lightcache crash with environment map

[bhchllc]

I'm having a very weird problem with Lightcache crashing when there is an environment map loaded. Everything renders fine with no environment map (background map). There are some other weird things though so I will go through my tests.

I have 3 identical machines, on which the error only happens on two of them (AMD MP2800, 2G ram). I aso do not get the crash on a dual 2.8 Xeon.

The error happens with any file, even new simple "teapot" files.

Yes, all machines can "see" the map.

As stated above, unchecking the "use map" toggle in the environement dialog window allows everything to render fine.

It isn't a memory issue, I've created a tiny 100 pixel map and still get the error... it is spherical.

Error also occurs if I use the relection/refraction/env Vray override.

I've tried several maps to confirm it isn't a corrupt file but some machines can render it anyway.

This is the last few lines of the vray log before it crashes

Any ideas?

EDIT: It also appears that with an environment/background map enabled, these machines can not participate in DR either. Those same nodes fail.

I tracked it down to the infamous ColorCorrect plugin. I had different versions of the plugin on different machines and the one version was causing the plugin to crash the lightcache. I think the reason it was still doing it in my teapot scene was because I didn't do a Max reset and still had the fubared material in the MatEditor.
