some black buckets when rendering with DOF on one machine

[tobihofer]

Hi! I am rendering a scene (PFlow) and I am getting black buckets when rendering on one machine. Is this a bug within Vray 3.60.01 or 3.60.03?

Cheers Tobi

I believe this is alredy reported a few times and considered as expected behavior.
Increasing AA min subdivisions to 2 or 3 should resolve this issue, increasing bucket size could also help.

Lower AA samples cannot get enoung information in some arreas and thats why the dof is missing there.
Try to increase min subdivs and see if there is any improvement, if there isn't we might need to have a look at the scene.
