Bucket never finsihes rendering.

[animator75]

Hi!

I have a strange problem with a big scene (lots of Forest Pack trees and Laubwerk trees) At least one bucket is always left rendering and never finishes, the other buckets complete the render. It's like the individual bucket gets stuck in a loop. I am rendering using the BF - LC method. As a test I switched to the progressive sampler but that got stuck after 10 minutes of rendering. My first thought was not enough RAM, but I have 16 gb and the scene takes about 12 gb during rendering. I have tried to render it on my small farm through backburner and the same thing happens on all machines. Any ideas?

The best idea that comes to my mind is to send us the scene so we can take a look (support@chaosgroup.com / peter.matanov@chaosgroup.com)

Thank you! I will look into sending you the file this weekend. The scene is quite big, can you download it from my dropbox or do you have a FTP I can use? Also I tried lowering the samples in the adaptive image sampler to 1/4 instead of 2/12 that seems to work, but there is of course too much noise. At least it gives me some frames I can experiment with in my video editor..

Dropbox will be fine You can also set a region around the problematic area (if it's always the same) before you upload the scene.

Hi!

I have a same problem with a big Scene, in my case I have IM+LC, 40 millions polys, my server has 64gb RAM.

In a scene I'm working on sometimes I have buckets that never finish (as if they were in a loop), the rest of the buckets run correctly and finish the prepass phase.

The problem is that the buckets that are stuck never finish and the prepass crashes and stops the "current task" timer.

I have attached two images.

In the first one if you look at the number of the FARM it looks like some other farms are trying to do the same bucket (you can see numbers overlapping in the picture, next to "FARM").

In the second picture the problem is that the Farm has finished the bucket, but the bucket remains in black..

Thanks a lot.

This problem only happens if i use Backburner. In Local machine with FARMS runs correctly.

Any chance to send us that scene for investigation?
When using Backburner, are you also using V-Ray DR or each frame is send to a separate machine?

Let us also know the exact versions/service packs of V-Ray,3dsMax,OS and BackBurner.

I,m creating only one frame, i use only V-Ray DR with BACKBURNER.

Vray 3.30.05

3ds Max 2016 (64-bit)

Windows 10

Backburner TM 2016.

If I launch the render with my local machine with V-RAY DR the render runs correctly.

My render crashes when I use Backburner. I have a machine using BACKBURNER (name: farm-6) with MANAGER AND SERVER. This machine calls the rest of the servers (farm-1, farm-2...), and starts the render, LC works fine. Our problem comes when the processing IM.

Thanks a lot.

It is really recommended to update to the latest V-Ray 3.40.03 and see if the error is still there before taking other actions.
