ZDepth render layer not showing up in Nuke

[luxvfx]

Hello,

I am having an issue with zdepth passes not showing up in Nuke. If I save out a multichannel exr from the render buffer and bring it into Nuke the depth pass is there as expected. Once the scene is submitted to Deadline and I bring the sequence into Nuke the depth pass is empty.
We are rendering out a 16bit multichannel exr with Maya 2018 and VRay Next. Our Nuke version is 10.5v7.

Any help with this matter would be greatly appreciated.

Thank you!

I can't manage to reproduce this behavior. Can you attach a simple scene? Does it only happen with a particular scene?

Hello,

I have uploaded a sample scene as well as 2 separate EXR renders to Google Drive-- one saved from the frame buffer and one batch rendered through Deadline.
This problem is affecting all of our scenes and only occurs after batch rendering.

Let me know if you have trouble accessing the file.

Thanks!

Please unchek multi-part exr and try again.

Hi Dmitry,

Thank you! That solved the problem. Is this a bug or intended behavior? We didn't have this issue with previous versions of VRay.

I am not sure, I had issues with multi-part exr reading in older nuke versions at all.

Hello,
I have the same issue. How it’s possible then, to get multiple channels in one exr when it is not rendered as a multiExr?
thanks

multi-part exr and multichannel exr are different things. I think multi-part is used to optimize the pixels in different channels you do not need to use multi-part to get multichannel exr.
