Dark buckets

[glorybound]

Everything was going fine and now I am getting black buckets. They show up only with GPU mode, even with DR disabled.

[glorybound]

Nobody! went away and came back in a different form.

It's showing up in the reflection pass

[vlado]

Are you using the bucket mode for rendering, or progressive? Can you get me a scene for this as well to vlado@chaosgroup.com ?

Best regards,

[glorybound]

It only happens in bucket mode. I turned of my VRay Sun/Sky and it stopped.

[vlado]

Ok; I think we may have fixed this recently, having an example scene to verify will be extremely helpful anyways.

Best regards,

I will send that over to you, thanks!

I know GPU is kind of new but isn't it mature enough to use in production? I can't get a render on this one without strange boxes, even without the sun/sky. I waited a while to jump on board, but maybe it's too soon.

I am also getting a lot of these reflection errors. One thing I noticed with NEXT is, the reflection was never the same. My exterior glass sometimes has absolutely no reflection, even in the reflection pass, so I have to use the RAW reflection pass. I have noticed that GPU doesn't have the RAW reflection pass.

Any progress on hunting down the culprit?

I know it’s not a solution, but does it occur with LC disabled and BF/BF?

I'm having the same problem with an interior scene. I have GI, TotalLighting, reflection, refraction, specular, etc RE and the problem seems to appear only in the GI pass.
I'm rendering from an Intel machine using a Threadripper one in DR mode, maybe it has something to do with that...

If change to BF/BF as danio mention, the problem disappears.

BTW in my case the problem occurs with CPU rendering in bucket mode

[glorybound]

I'll try BF/BF and report back.
