Some portions of render not showing reflections.

[loac]

I am having an issue that appear to be certain ‘buckets’ not rendering any reflections. I am using distributed rendering but it is strange because the squares without reflections always stay in the same place. Where if it was a problem with dist rendering, it seems they would move around depending on what system renders that square.

I am aware of a ‘black squares’ bug, but this seems to be a different issue possibly.

Thanks for an help you can give.

I am on Vray 1.60.16 on Windows XP. With a 3ghz Xeon and 12 GB ram.
