Hi, I haven't found any question like that, so excuse me if there is any.
Whenever I use distributed rendering, there is a chance (about 25%) that the render will have some buckets shifted.
Also there is like 75% chance that buckets rendered by a different computer will have lower opacity - alpha channel will have grey buckets.
All computers have the same version of vray and sketchup. Sometimes the render is just fine and I haven't found any connection with any reason of the problem.
Thank you for your help.
