error - set region problem

[tricky]

I left a render going last night on my local machine. Vray 1.5, Max 2009 x64. Here is a portion of the vray log:

Yep, there seems to be a problem writing tiled OpenEXR files that take a long time to a network location. Writing to the local disk, or to a .vrimg file is not a problem.

Vlado,
Has there been any solutions to this problem? Apart from saving to VRIMG that is.
I am still getting this error but it is never consistent. Some machine render everything fine then others have the error. Then that same machine might render another image and everything works!

[vlado]

No, unfortunately I haven't found a fix. But, OpenEXR 2.0 is just around the corner and hopefully it will handle this without problem

Best regards,
Vlado
