Buckets don't match up

[pvanhaitsma]

I'm posting this in hope that someone has had the same problem. Forgive me if this has been discussed already. I'm having issues with my buckets from other machines I'm using for DR to match up. As far as I can tell it isn't because of missing maps. I'm working on an older file and bringing it into 3.0 from 1.5. The current project I'm working on was fine until I started copying large amounts of objects in the scene.(which probably has nothing to do with it) Anyway, when I render I get buckets that are darker or lighter than each other. I'm really at a loss for why this is happening. Any help or suggestions would be great. Sample image attached.

Hi,

Is it possible that some of the plugins used in the scene to be unavailable for the render slave machine?
Actually I see three different buckets in this image. Are you using two DR machines ?
Does it happen to the entire render frame?

I am using two render slaves, and like you noticed each one comes up different. The best I can tell is that any surface that has a reflection is affected and it happens throughout the entire render frame. I don't have any plugins installed or being used. Whats odd is that sometimes its fine but it always seems to come back. I've heard of different processors or machines rendering slightly different but the DR slaves seem to be completely omitting the reflection of objects.

Thanks for the update.
Would it be possible to create a ticket in our support system about this issue. Just send us an email to support at chaosgroup.com including the full spec of the machines, OS, exact Max/V-Ray versions.
But can you try first to add Reflection, GI, Diffuse and Lighting render elements and see which one/s have the bucket issue?
Also, please make sure that all machines has identical V-Ray versions installed. The same applies to the Max Service pack.

Here is another example of what I'm seeing.

It doesn't look like a gamma difference for me. Seems like there is a big difference in the lighting.

Do you have "Transfer missing assets" turned on under DR settings? Ive had this happen with missing maps and with different versions of plugins and or service packs.
