Render wrong buckets, looks a little correct but not 100%

Hi.

I have a problem with my renders. Some buckets does not show up correct. What can be the problem.?

Are you using distributed rendering? Looks like some of the render nodes can’t find the textures. (Or they have different vray versions.)

Yes. But I have latest Vray on both.

when I render with lower settings, I don’t have the same problem.

Hi,
Do you have any warnings in the V-Ray Log screen?
Be sure that all additional plugins (if such are used) are installed to both of the machines.
Do you use a preset for the lower settings?

I think I might have solved my problem.

I had to update my forest pro on the render slave.

But know I am dealing with crashes during rendering. Almost at the end of the render:(
