DR problem dark / bright buckets

I´m having a strange problem with dark / bright buckets and my renderfarm.

All bright buckets are rendered with the DR renderslaves, the dark one by the main machine.

I´ve set “,” and “.” correct on all machines and checked gamma settings an all.

The problem sometimes appears and goes away and I don´t have any idea what
causes it.

This is on 3Ds Max 2010, VRay SP5.

Funny, i’m still getting this problem occasionally, with no real ideas of what is going on.

Gamma appears to be normal, all maps are visible, whyyyyy!?

So, as per the usual, whining on an internet forum made me check something else.

the offending machine was using an older Vray version.

Pardon.

Hi,
Do you use same V-Ray versions for both, renderfarm and workstation?
Also please post V-Ray log files from them, immediately when you get this error, so we can investigate further.
Another option to check is " check for missing files", and equalize your 3DS max Gamma/Lut settings.
Could you specify which machine gives the correct render result, the renderfarm or the workstation?
