Deep exr with overscan is offset from beauty

Hi,

With overscan enabled, deep exrs rendered from maya appear to be offset in X by the amount of overscan (vray_deep_offset image), and don’t line up with the corresponding beauty rbga. If I disable overscan, the deep image lines up (vray_deep_no_offset image). I’ve tried different combinations/types of overscan with the same result. Anyone come across this?

I’ve attached a simple example file that renders the attached images.

Maya 2023.3 on Windows
V-Ray 6 for Maya, update 1
(v6.10.00 from May 15 2023)

Thanks,
Chris

I’ve reported this issue, are you using nuke to load them? I believe its a nuke issue rather then vray issue. They should be offset back X -300 Pixels (if its HD). Or you have to render with old school overscan where you use camera scale, then it works fine.

Thanks for the report. We already have the issue logged (internal bug-tracker id: VMAYA-8402). I’ll ping the project manager about it.

Thanks for the info @hermit.crab . Any eta for a fix?
@Morbid_Angel I don’t believe it’s a Nuke issue, as a deep rendered with Arnold does not have the same problem.

It’s funny because I was repeating what Chaos told me at the time, this was some years ago though. Hope it gets fixed.

I am getting something very similar - Vray 6 in Maya 2025. Batch render from same scene, not with overscan but with limited data window. Beauty and Deep are misaligned by a lot:

​Bit of further investigation and it seems that Nuke’s DeepRead is giving hte error. Reading same file into a normal Read and it aligns. However Overscan disabled in Vray the issue goes away. So appears to be a miscommunication between the 2 apps?

Thanks for the report. I can confirm it also happens with the EXR’s data window. I’ve updated the log and informed the project owner about it so as to increase its priority.

Thanks Aleksandar! I can confirm that disabling overscan in the render settings seems to fix the issue even with data window enabled.
